Animations not changing or not working

Hi so I made an animation and i wanted to test to see how it looked but when I went to change the animations id in the players animations it sometimes wont even change the animation or just not work, I am aware that you need to own the animation to use it but as you can see in the video I do own the animation Streamable

can we see the script?
–characters–

what do you mean by that???

the script that changes the animation id

I got it to work but thanks tho
