I watched the parameter extended cut video but it did not address my problem. I have vb code setup for double click on a field to open up a form. When I double click the parameter boxs opens and asks for the parameter. When I enter it, it opens the form. Both tables have the same field and neither fields are the primary key. Not sure what I am doing wrong. There's are no typos in the code. Can this form open up w/o the parameter box?
