How do I move instances one by one to a target position when a condition is met?

I'm stuggling to make a bunch of the same object to move to a specific target when a condition is met (or a button is clicked), one by one. That is, when clicking the button, move one instance to the target position

This is what i've got

It moves the first on but not the others

Thanks

You want to use the system pick nth instance condition, and use an incrementing counter (increase variable by 1) to specify which one to move.

Thank you oosyrag

That was it!
