Thanks for your help. Still struggling and I think I have messed up my question. I will start again and thanks for any further help. You must get sick of we novices asking what no doubt are simple problems. I have created a new simple demo file called 'CardsMyExample' and uploaded it. It has two tables TYPE (eg. MasterCard), and CARDS. My thinking is one Card Type (Mastercard) can have many users (Lyn, Greg, etc). That is the relationship I have created.
But when I add a new record on the CARDS layout and select Mastercard from the Type dropdown list (which is the only option so far) I keep getting new unwanted entries as seen below.
Just cannot work this out!!!
