Form-Add New-"Can't Set Value to Null...."

[LarryP]

Access 2K -- have a form where sometimes the user will want to add a
completely new record. Whether he clicks the built-in "*" or clicks on a
button I've programmed to take him to create new record, an error message
appears: "Can't set Value to null when checkbox property = FALSE."
Actually, this message appears multiple times.

I can't find anything in my code that would cause this, and since it also
happens with the built-in "*" feature, I suspect it's a system issue rather
than something I did in my code. Can anyone edjicate me?

Can you post the code so we can look at it?
