I have Dsum calculation in a query to display the summation of a cost per
piece in a subform which is based on a query which is based on a table.
However It does not change or update the summation of cost per piece unless I
close the form and reopen it. I have tried requery on one of the fields
(Speed Field is the name) on the LostFocus event but it doesn't work /
refresh the correct summation when a speed is changed. The speed effects the
cost per piece. How do I accomplish this? Am I using the correct calculation?
Should I VB Code it? Any help would be appreciated.

THanks, Kyle.

My Calculation is the following.
CostPCSum: DSum("CostPC2","QryDataSub")
