Auto add records

Auto add records

Hi 
I would like to create a new record in a form & then when submitting it automatically create a number of new records in a second form based on a number in the first form.

I have a "Print" & then a number of "editions" of that print so that when I add the "Print" details I would like to create an edition record for each number of the "edition".

How would I do that ?

Thanks

Derek
