Hi Ken,
Thanks for replying.
Basically, I have two queries GoodsIn and GoodsOut which calculate what comes in and what goes out. A third query calculates GoodsIn less GoodsOut and comes up with the OnHand figure.
What I'm trying to do on my form is reference the OnHand figure for the relevant product.
I tried to include the OnHand query as part of the underlying recordset of the form but this makes the form non-updateable.
