I am sure I have done this in the past with no problem. I have a form (Form1) and a subform (Form2). They are bound to related tables. On form 1 I have a listbox (List24), which has rowsource query, the list sets the underlying form to the selected record when clicked. All okay so far. However Form2 (Subform) has a listbox, rowsource query, with the ID field criteria being bound to Form1 List24. It should show all records related to that ID. However the parameter for the field keeps getting asked for by a dialgue box, its driving me up the wall. The parameter inside the query of List2 on the subform is =Forms!Form1.List24
Done it so many times before I am sure. Thanks
