Default Conversion from type 'DBNull' to type 'Boolean' is not valid.


This is my second time trying to post this to this site so I appologize if its a repeat as the the first one didn't appear to go through.

I'm new to and am getting the error posted below. I have a formview and it contains fields OT and PT, which are set in the DB as allowing nulls. From what I've found googling this error, I will need codebehind but do not know what to write or what event to post in under.

Any help would be greatly apprecited.
