How do I check if X instances are overlapping one object?

So I have a weighted button in my game that requires a minimum of X creatures overlapping it to press it. It works mostly as expected, but when I have multiple instances of the button, as long as at least one is overlapping it it checks all instances (So if button A is overlapping 2 creatures and button B is overlapping 1 creature, both buttons count it as overlapping 3)

How do I fix this?

Here is a screenshot (Ignore the disabled events, that was a different method I tried with the same results) Note that the animation frames being set to 1 or 0 just means pressed or not pressed, respectively.

Probably something like 'for each button, creature is overlapping button' > set button.variable to creature.pickedcount might work.

It works! Thanks for such a quick response btw
