Animations not working in the Edited FE Gun Kit by thienbao2109, help? [closed]

So, I made some animations for a gun which uses the Edited FE Gun Kit by thienbao2109 but I can't find any spot where I can put the ID in. I've got some screenshots of the section in the script where I think it needs to go but if I put something else as Nil in it, it will just break the gun. Where do I need to put the animations? By the way, I am using R6.
