When I try to put a command button into my customer form to open the contact form and the command button wizard opens, the section where I am suppose to match the fields on the "CustomerF" doesn't contain any fields at all. What am I doing wrong?

Reply from Alex Hedley:

Is your RecordSource a SQL statement instead of a Table or pre-made Query?

Do the Foreign Key Fields match, i.e. CustomerID in CustomerT and CustomerID in ContactT?

Or try the usuals, Save/Close/Reopen the Form.
Save/Close and Open Access
Backup then Compact/Repair.
