Ok, now uncomment this code one in a time. E.g. first try to uncomment only the RecordSource portion and leave out the Header's assignments code.

I usually don't include buttons in the form's class... Anyway, put

set step on
return dodefault()

into the old cmdReturn to see, what is actually happening...

I guess, this is the hard to crack case. Sergey in his FAQ pointed out all known to me causes of this problem. I had such error messages myself, but was able to overcome them every time...
