How to check multiple buttons in one procedure?

For the mod I'm currently working on for a system to increase and decrease three values I needed 6 separate procedures, since this isn't the only logic in the GUI it comes out to over 10 which makes it all incredibly messy and since I have a second one of this with just different values, yea it's even more of a mess so is there any way to give a procedure a value on call or, well the more effective one, letting multiple buttons be managed by one procedure?
