Cant copy and paste keyframes from one animtion into another animation

Hello,

Im trying to add a walking animation i made a while back into an animation im making now. Im just using the copy and past method, i can copy it but when moving over to the other animation there’s no option to paste

It works for other animation’s though where i can copy and paste those, but i need to paste this one specifically and i dont know how to fix it

Does anyone have a solution to this problem?

So you are saying that you have been able to copy and paste keyframes between animations in the past?

Are you using the same rig?
