Datagrid Template Column - Radio Button Bind

Hi.

I have a datagrid that has 4 radio buttons per row.  Each radio button is a seperate question (rb1=question1, rb2=quest2) etc... I am successfully able to submit the answers of each row into the database.  Now the problem is, I need to populate the datagrid and then using the datagrid results I also need to populate the answer of the radio buttons.  The results that populate the datagrid and radio buttons are two seperate stored procedures:

SP1 for datagrid is retrieve all applications:
So it returns:
Appln_id and Appln Name
1   App 1
2  App 2

SP2 uses the given rows Appln_ID and then populates the answers (using that appln_id)   into the RB controls:
1  App 1    RB1=Checked            RB2=Not Checked....
2  App 2   RB1= Not Checked      RB2= Not Checked .....

Right now, I first populate the datagrid with the appln_id and appln names.  Once the datagrid is filled with that information I go back and do a loop through each row, passing in the rows appln_id to help populate the rb answers (each rb is a different question id so I have to loop through each rb too).  I cannot seem to get the rb's to work.  I keep getting the error "object reference not set to an instance of an object".  I ran the sp and I am certain that the values I"m passing in return an answer (to eliminate all problems).

Here is the code.  Please help me debug this!  If you think I should be following another method, please let me know!  Thanks!

Do you see anything wrong with the section I said had a problem?
