Hello - I'm currently trying to develop a small app to help me keep track of my eBay sales. I entered all data into excel, exported it to access and let the VB.NET data form wizard do the rest. It was working fine until I attempted to add a combo box. Now it throws:

An unhandled exception of type 'System.InvalidCastException'
occurred in mscorlib.dll
Additional information: Object cannot be cast from DBNull to other types.

This exception is thrown after the "Add" button is pressed, which used to just add a new row to the database upon which I could add my data. Does this ring any bells with anyone?? Any help would be MUCH appreciated!!

Thank you!
Sincerely,
Reid V. Plumbo
