Subform with combo boxes

[stampr18]

I have a form (orders) that contains a subform (order details). I have several combo boxes in the subform that works fine with the subform alone. When I go to the form and try to use the combo boxes, it wants me to enter a parameter. The parameter is in the previous combo box. It's not reading the parameter from the previous combo box in the main form, but it does when you use the subform by itself.

I would really appreciate any help with this.

You haven't referenced the full Form/Subform correctly, open the Main form in design view and use the CodeBuilder to drill down and obtain the full reference

Can you give me a little more information on Code Builder? I know how to get to it but that's about it.
