Yet another Wire question!

I need to make some kind of a system that when I press a button it increases the value of something by a certain amount. For example a forcer engine (actualy what I need this for :P). I press the + button and the power values of every forcer in the system increases by 10. I press the - button and the opposite happens! Mah question is how do I have to wire it? (and please no expression 2…)

Spawn an Increment/decrement chip under Gates -> Arithmetic:

I1. Wire a constant value of 10 to “A”
I2: Wire the + button to “Increment”
I3: Wire the - button to “Decrement”
I4: If you want, wire a seperate button to “Reset”

O1: Wire the output to whatever you want.

Thank you =).
