Thanks for the help, but unfortunately that expression doesn’t do what i wanted it to do. Let me explain it again but this time using a screenshot as well.

So basicly there’s my 2 keyframes that i’ve set to make an animation, and there’s the “Outro” layer at the top of wich the end is touching the end of my range. And what i want to happen is that when i change the end of the range and more the “Outro” layer i want the keyframes to move with it. Is it possible to achieve this?
