How would you and is it possible to make a calculation on 2 different list boxes. I have an unbound form, I have two listboxes.
[list1] and
[list2] Which both listboxes are based on there own querry List box 1 is query 1 and list box 2 is query 2. Both list boxes produce a sum total which is displayed on the form. However, I would like to take the value of List1 and subtract list2. Tota:
[List1]-
[List2] Is this possible and how?
