Constraint Editor Problem/Question

[Leo Graywacz]

I have a panel that I am trying to constrain. It has a top, bottom and middle rail that are 2" wide. The panel spaces will be equal no matter what the height is. I have constrained the T, B & M rails at 2" and I want to use a formula for the panel. What I need is (h-6)/2 but can't get it to work. I have tried a bunch of variants of the same formula but it gives me answers that aren't correct. What is the correct formula to get this to function properly. Thank you.

Never Mind, I figured it out. Or, there was never anything wrong. The program was just having some issues and when I restarted it, it was working correctly.
