 So you just want your button to increment a value, not a problem. Let's just say that you have a variable for an index and every time you click this button, you wanted that index to subtract by one. Well, to do that, go to your standard button click trigger, then drag out the variable wants to get and wants to set, then from the get drag and type negative in order to subtract one. If you wanted to add one, you would just type plus instead, we want to subtract, so we're going to use negative, then connect them together like so you're done. Now, every time you click this button, it will increment by negative one. Hope that helps in as always, hope you have a fantastic day and I'll see you around.
