My animations for my Bloxikin (type of body) StarterCharacter are not working

So, i have been working on the animations for my pvp game with bloxikins lately and for some reason the animations dont load
or the character straight up doesnt moves.

1- Before i started animating the character, i used upper torso and lower torso, and the character moved without any problems and animations. Could that be the problem? i dont think r6 supports two torsos but idk…

2- Am i using the wrong animator plugin? i heard theres a modern default animator, but for some reason i dont have it on my inventory nor it appears on the store. So i used the classic animator. Could that be the problem?

I watched tons of tutorials on youtube and still none of them work even if i did all the steps correctly.

what do i do?

edit: im not an experienced scripter and animator btw. i only know the basics.

could you tell us what you are doing exactly?
is the game under a group? did you change the IDs in the animate script?

First of all, i made the character (torso, legs, arms and head, root)
Second, renamed them and rigged them. (Torso connected to root and all the parts connected to torso)
Third, made the walk animation (and then uploaded it)
Fourth, scripted the animate thing

And then it doesn’t works.

i added the humanoid part, savedanims and all that stuff btw.
