Using Access 97, I have created a main form using tab control pages. There are three underlying tables all based on the one primary key. I am attempting to insert two subforms into two different tab control pages. The problem is when I try to enter records, I receive this message "The LinkMasterFields property setting has produced this error: 'Ambiguous name detected: Last_record_click'". I get the same message if I try to use command buttons in the tab control page. What does this message mean given that the relationships between my tables could not be simpler?
