Hi

Thanks for replying. Yes I use set relation in the IDE. I have the child key set and it works fine.

The problem arises when I open the table in my form. For some reason it changes the key and the relationships even though I have deleted these. the table has a foreign key specified linking to the customer table.

I'm not sure why this is happening. Any ideas???

regards
Geoff Scott
