Hello Filemaker community,
I've attempted to solve my problem via google, however since I'm a novice in Filemaker, I don't know what I'm looking for is called, therefore can't search for it very well.
I'm looking to have a button with an on/off function that modifies the numerical value of one or more fields. For example, I would like to have an invoice layout with a button labeled "Fee" that once pressed would add lets say 5 to the field "A" AND subtract 2 from field "B". Fields A and B would already have a numerical value manually input by myself. When I press (or depress in this case) the button again the values that were added would be removed (-5 to field A, +2 to field B in this case). As gravy, I'd have more than one button affecting the same A and B fields with their own specific values.
So multiple buttons that once pressed modify the value of multiple fields with different values for each field modified. The button would have an on/off function so that once unpressed remove the modifications.
Is this within the realm of possibility? A script perhaps?
Any help will be greatly appreciated.
