hey Gina,
I looked at your database and I just wanted to know everything worked...
You put a requery on the transmission cost - why should you do that and not on the Total Cost.
Also was the only other change you made was the VBA code under subform1 for On Current?
I copied that code into my database and I don't get the #Name error anymore but it is still not updating the field with the total amount from subform2. I have put a requery on the Total field there?
Should I be doing anything else?
