I have a form with a working list box. But when I insert that form into a tab control form, clicking the reports on the list box will give an error message. Attached is the db. Appreciate any advise on how to solve it.
Your problem was the macro was calling the listbox instead of the report. Hopefully you can live with VBA for this because it's very easy in this case and I did it for you so you can see how it's done.
You may want to check out this page for some quick tutorials (screenshots) for some of this.
