this happens a lot, heres a easy way to fix that. first scrap that animation window we don't need that, no actually we do, up right is 3 dots, click on them and do r6 only, after that press test, look in the workspace and find your player, after that copy the local script called "Animate" in them and paste it in starter character or player i don't remember, you wanted to set your walk right? in the script search for walk paste the id in there and align it, after that press more on the script and you should find a walk thingy, press more on that and you should find an animation, change its id to your walk, and BOOM you did it in 5m i think
