I have a javascript button I am trying to create to update a picklist field on a custom object.  Here is the code for the button:

{!REQUIRESCRIPT("/soap/ajax/29.0/connection.js")}

var p = new sforce.SObject('Projects__c');
p.id = "{Projects__c.Id}";
p.Status__c = "Closed";
result = sforce.connection.update([p]);
location.reload(true);

The code is not throwing errors on the object it is just not updating the field.  The page is reloading. Anything wrong with the code?
