How do I have button click update global variable only once per click?

I have something like a binary tree/choose your own adventure mechanic. I present multiple questions and the user can go right or left at each question. I keep track of this with a global variable called questionNumber. When the user clicks buttonRight, I would like for the global variable to be updated only once. However, with my current set up, the global variable is going from 0 to 2 to 6 to 15 from just one click.

You could get rid of the trigger once they're not needed and replace them with Else except for the first condition, it would work.

The events inside the triggered event are still working top to bottom. So if your variable is 0, in that tick it is set to 2, then also within that tick the next condition is true, so the variable is set to 4 and so on.

Add "wait 0" before the actions in each sub event so that the condition check happens once in the first tick, and then the variable is not updated until the following tick.

And yes, you don't need the trigger once conditions.

The "wait 0" did work. Also, right after I posted I tried reversing the order and that worked as well. Thank you!!
