Novice question:- I have persuaded a pop-up form to appear for enquiry and entry of additional data, but the pop-up appears to refer to the first record in the table, not the same record as on the original form as intended. I think I want to retain the Current Record gizzmo. Access ver. 7.0 is trying to help me........

This is exactly what Fornation told me to do when I had a similar problem:

Try setting the default value of the linked field in your pop-up form to the primary ref on the parent form - Forms![MainForm]![IDField].

In other words, you should have an ID field on both records and you need to set the default value in the ID field of your pop-up form to the same ID value as your main form

Thanks SomeGuy and Fornation.
The reply did not instantly fix my problem, but it did alert me to the notion of primary references. Now I am making more progress through reference books and help files.
Thanks for being there!

Another option might be to create a subform and let the wizard link the two forms, then make the subform visible or invisible whenever you like.
