In the newest posted form, the CougarnetID field never gets set to the field1 value. I have been successful at using the Username() function to directly set the CougarnetID field directly, "field1" was a field I added for testing purposes, it doesn't exist in the list, just on the form.
In addition, the GradDegree field never gets set to the list value, but I suspect this is the result of the CougarnetID field not being set.
