But just answering due to the question can be extremely misleading, especially if you start adding tables to a query it can easily become non-updateable. So, yes I understand where you were coming from. But I'm coming from a spot where I see too many people trying to do too much with a single form.
Hehe!! I know what you mean What the OP will then realise is that his original idea of a single form approach isn't working and come back on here for more advice. A good way to learn sometimes
