How do I Move a ui element by uid

I'm making a Turned based combat system currently. and I can't get the arrow when selecting an enemy to move. at first, I thought let's pick by furthest that moved but didn't scroll like how I wanted it to. next, I tried picking it by a variable that acts as an ID. now it doesn't even move and I'm highly confused

And without posting your project, I'm afraid all other users also are and you will not get an answer.

Or at lest show the relevant code of your event sheet so we can tell you, what in the logic would not work.

ill post the Capx if needed
