I have the same problem but not that complicated. So do anyone know how
to subtotal only one field value in subform? I only found sum which only
used for table but I didn't found functions for subtotal a field in
subform. If possible can anyone give me a simple sample for the function
of subtotal? (I am just a poor business consultant who was trying to
code in Adobe, so this request may seems **bleep**) Very appreciate.
