HELP!:DBNavigator Problem

I'm working on an application in which I have several forms. Each form has a
DBNavigator.  Each time I click on the Insert button to add a new record I get an
"Invalid variant type conversion" error.  This happens on each form, no matter what
database(s) I'm using.  I'm stumped.  Any ideas, anyone ?
