I've got an apex class that contains an aggregateresult. I'm having a hard time getting my test class to cover that section.  Anyone know why? 
Thanks for your help

I've been trying do many methods to get this accomplished with no success. 
I have two visualforce pages and one controller. 
The first visualforce page consist of three select list fields - a search button and a generate report button
The second VF page, renders as PDF and essentially renders the requested report.
The controller contains methods to search based on the select list inputted from the first visualforce page as well as methods to List the required data in the report.  One is a simple list and the other is an aggregated list. 

My issues is that I'm having a hard time getting the where clause in my list and aggregated list to work and filter to show the filtered data on the report.  
The search filters well and the results are correct, but whenever I try to fitler (where clause) by the same string on the other list, the second visualforce page just shows the results.  If I remove the where clause then everything works but the report shows me unfiltered results. 

Code is below.  Any help would be appreciated.  I'm new to this so any help would be appreciated.
