Populating A Form, Dropdowns Not Working

Hi All,

I have literally spent the last 2 1/2 hours troubleshooting an issue where I pass a parameter to the page and based on the parameter it runs a SQL statement and fills in the fields on the form.  It is giving me the error message below but I know its not a NULL value and I know those controls are named correctly.

System.NullReferenceException: Object reference not set to an instance of an object.

All of my textboxes and labels that are being populated are working fine when I comment out the dropdowns, I have this working on other pages but the only thing that is different here is I am using some AJAX (Autocomplete, Collapsable Panel and Calendar Control). 

If I add a label or a textbox field on the form and take the same value that is going to populate the dropdownlist and populate the new control it works, so i know I'm getting the data and its not null/nothing.  I also verified that the parameter is working correctly. 

Any help will be a blessing, its probably something write under my nose!
Thanks in advance!
Tim
