Hi all,

In form, I want to calcuate sub total(txtsubtotal) that get valule from total(txttotal).

txttotal= Qty*Price then txtsubtotal=sum(txttotal). it won't work but if i write txtsubtotal= sum(qty*price) it works.



How can i calcuate value direct from txttoal? please help.

Thanks for your answer.

If I want to sum a calcuated control, how to do? Absolutely, We can't ?

I already said you couldn't. Maybe you'll believe Microsoft.
