Gui tweens up rather than down?

Not sure how to fix this, I’m just trying to make a generic cooldown tween

You really haven’t provided us anything to work off of, have you tried flipping the direction of the tween (ex tween opposite direction)

I mean… I’m tweening the size, not sure that’d do a big deal

If you are tweening the size, sometimes you will need to tween the position at the same time in order to get the desired result, or you can tween only the position and leave the size alone. If it is sliding out of another frame you can check on the ClipDescendants property on the parent frame, if its sliding out of view then it wont matter anyways. So those are most likely your two options

Can you show us the code you have written?
