So as I always like to start each conversation, I consider myself a freshman to sophmore developer.  I'm digging in and trying to learn so I very much appreciate all the help!

In the Salesforce1 Workbook, they talk about the Enchanced Warehouse Schema app that you can install onto an org and then build out a visualforce page to utilize the googleMapsAPI static resource (which is a javascript).  On my first "sample" Org I installed the the package and I can successfully run the pre-packaged Completed_FindNearbyWarehousesPage.

So far so good.

Now..since I'm a glutton for punishment, and I really am trying to learn the "guts"...I wanted to build this out manually in a second test Org. 

I created my Warehouse object and the necessary fields. 

I then uploaded the googleMpasAPI javascript as a static resource. 

Next I built out a visualforce page simply called FindNearbyWarehoursePage. 

However, on the org where I tried to build out manually vs. installing the package, my VF page doesn't return anything.  However on the org where I installed the package, the page resolves to my current location.

Now...for the details......

First...my class, FindNearby.

global with sharing class FindNearby {

    public FindNearby(ApexPages.StandardSetController controller) { }

    @RemoteAction
    // Find warehouses nearest a geolocation
    global static List<Warehouse__c> getNearby(String lat, String lon){
    
        // If geolocation isn't set, use San Francisco, CA 
        if(lat == null || lon == null || lat.equals('') || lon.equals('')){
            lat = '37.77493';
            lon = '-122.419416';
        }
        
        // SOQL query to get the nearest warehouses
        String queryString = 
           'SELECT Id, Name, Location__Longitude__s, Location__Latitude__s, ' + 
               'Street_Address__c, Phone__c, City__c ' + 
           'FROM Warehouse__c ' +
           'WHERE DISTANCE(Location__c, GEOLOCATION('+lat+','+lon+'), \'mi\') < 20 ' +
           'ORDER BY DISTANCE(Locatoin__c, GEOLOCATION('+lat+','+lon+'), \'mi\') ' +           
           'LIMIT 10';
           
           // Run and return the query results
           return(database.Query(queryString));                
    }
}

Next up...my googleMapsAPI javascript that I uploaded as a static resource.

window.google = window.google || {};
google.maps = google.maps || {};
(function() {
  
  function getScript(src) {
    document.write('<' + 'script src="' + src + '"' +
                   ' type="text/javascript"><' + '/script>');
  }
  
  var modules = google.maps.modules = {};
  google.maps.__gjsload__ = function(name, text) {
    modules[name] = text;
  };
  
  google.maps.Load = function(apiLoad) {
    delete google.maps.Load;
    apiLoad([0.009999999776482582,[[["https://mts0.googleapis.com/vt?lyrs=m@229000000\u0026src=api\u0026hl=en-US\u0026","https://mts1.googleapis.com/vt?lyrs=m@229000000\u0026src=api\u0026hl=en-US\u0026"],null,null,null,null,"m@229000000"],[["https://khms0.googleapis.com/kh?v=135\u0026hl=en-US\u0026","https://khms1.googleapis.com/kh?v=135\u0026hl=en-US\u0026"],null,null,null,1,"135"],[["https://mts0.googleapis.com/vt?lyrs=h@229000000\u0026src=api\u0026hl=en-US\u0026","https://mts1.googleapis.com/vt?lyrs=h@229000000\u0026src=api\u0026hl=en-US\u0026"],null,null,null,null,"h@229000000"],[["https://mts0.googleapis.com/vt?lyrs=t@131,r@229000000\u0026src=api\u0026hl=en-US\u0026","https://mts1.googleapis.com/vt?lyrs=t@131,r@229000000\u0026src=api\u0026hl=en-US\u0026"],null,null,null,null,"t@131,r@229000000"],null,null,[["https://cbks0.googleapis.com/cbk?","https://cbks1.googleapis.com/cbk?"]],[["https://khms0.googleapis.com/kh?v=81\u0026hl=en-US\u0026","https://khms1.googleapis.com/kh?v=81\u0026hl=en-US\u0026"],null,null,null,null,"81"],[["https://mts0.googleapis.com/mapslt?hl=en-US\u0026","https://mts1.googleapis.com/mapslt?hl=en-US\u0026"]],[["https://mts0.googleapis.com/mapslt/ft?hl=en-US\u0026","https://mts1.googleapis.com/mapslt/ft?hl=en-US\u0026"]],[["https://mts0.googleapis.com/vt?hl=en-US\u0026","https://mts1.googleapis.com/vt?hl=en-US\u0026"]],[["https://mts0.googleapis.com/mapslt/loom?hl=en-US\u0026","https://mts1.googleapis.com/mapslt/loom?hl=en-US\u0026"]],[["https://mts0.googleapis.com/mapslt?hl=en-US\u0026","https://mts1.googleapis.com/mapslt?hl=en-US\u0026"]],[["https://mts0.googleapis.com/mapslt/ft?hl=en-US\u0026","https://mts1.googleapis.com/mapslt/ft?hl=en-US\u0026"]]],["en-US","US",null,0,null,null,"https://maps.gstatic.com/mapfiles/","https://csi.gstatic.com","https://maps.googleapis.com","https://maps.googleapis.com"],["https://maps.gstatic.com/intl/en_us/mapfiles/api-3/14/1","3.14.1"],[3209180036],1,null,null,null,null,0,"",null,null,1,"https://khms.googleapis.com/mz?v=135\u0026",null,"https://earthbuilder.googleapis.com","https://earthbuilder.googleapis.com",null,"https://mts.googleapis.com/vt/icon",[["https://mts0.googleapis.com/vt","https://mts1.googleapis.com/vt"],["https://mts0.googleapis.com/vt","https://mts1.googleapis.com/vt"],[null,[[0,"m",229000000]],[null,"en-US","US",null,18,null,null,null,null,null,null,[[47],[37,[["smartmaps"]]]]],0],[null,[[0,"m",229000000]],[null,"en-US","US",null,18,null,null,null,null,null,null,[[47],[37,[["smartmaps"]]]]],3],[null,[[0,"h",229000000]],[null,"en-US","US",null,18,null,null,null,null,null,null,[[50],[37,[["smartmaps"]]]]],0],[null,[[0,"h",229000000]],[null,"en-US","US",null,18,null,null,null,null,null,null,[[50],[37,[["smartmaps"]]]]],3],[null,[[4,"t",131],[0,"r",131000000]],[null,"en-US","US",null,18,null,null,null,null,null,null,[[5],[37,[["smartmaps"]]]]],0],[null,[[4,"t",131],[0,"r",131000000]],[null,"en-US","US",null,18,null,null,null,null,null,null,[[5],[37,[["smartmaps"]]]]],3],[null,null,[null,"en-US","US",null,18],0],[null,null,[null,"en-US","US",null,18],3],[null,null,[null,"en-US","US",null,18],6],[null,null,[null,"en-US","US",null,18],0]]], loadScriptTime);
  };
  var loadScriptTime = (new Date).getTime();
  getScript("https://maps.gstatic.com/intl/en_us/mapfiles/api-3/14/1/main.js");
})();

Finally...my Visualforce page, FindNearbyWarehousesPage.  Note that when I load this page from my environment I'm getting a blank white page.  No error, the browser isn't asking if I want to use my current location or anything.

I even went so far as copying the code from the "working" environment to my "manual test" environment...and still I just get the blank page.  I must be missing something....but I'm at a loss as to what.  Could it be the static resource?  I uploaded the pure .js file vs. zipping it up.....

As always...I appreciate the time and insight!
