Like in Northwind, I'm trying to sum up the items on a subform and have them
appear on the form. I did the expression builder to sum on that field and
placed that field in the footer of the subform. Then when I try to transfer
that to the form I get the NAME? error.
 
Make sure the name of the field is not the same as the control source.

The Control Source of the mainform textbox needs to reference the name
of the Subform control - which might not be the same as the name of
the Form object within that control - and the name of the textbox on
the subform's footer.

Let's say the name of the subform control is MySubform, and the name
of the textbox is txtSum. You'ld set the Control Source of the
mainform textbox to

=MySubform.Form!txtSum
