Calculated value in a subform

C

CMTH

I do not know how much sense this will make...

I have a form that is linked to a subform by a service report number.
The subform is used to track parts used.

I have a seperate query that is used to show parts On hand. The query takes
all recieved parts (seperate form/subform) and subtracts parts used (above
mentioned form/subform).

Is it possible to include the On Hand calculation in the parts used
form/subform?
I would like to add a box that will show the current On Hand value as a used
part is entered.
