This has to be simpler than I'm making it! Trying to maintain column ototals ni SubForm, and update them to the MainForm.
Typical Northwind-type Orders-&-Details relationship: I extend row totals in the OrderDetails subform; and show OrderTotal (column total) in the SubForm's FormFooter. So far, so good. But when I change a quantity or price in the subform, I'd expect the subtotal to change automatically, no It does not; and I don't know whether I need to code a "Change" event myself, to modify that total whenever a single cell changes; and whether I must loop through the rows, or if there's a nifty group-operator in Access to do the columnTotal for me.
(I'm a VB programmer, reluctantly roped into writing an Access form.)
Finally, when I leave the Main Record (i.e., parent of the rows in the subForm), I want to store the updated suptotals in the Main/Parent record. (I know, I know, it's not kosher, but they pay me to do this stuff. -- Besides, it records what has been billed as it was billed; not as it's been updated since.)
Many thanks, anyone who can provide a cogent reply.
