I'm not sure if you guys might know this, but I really need help and if you guys can help that would be great because I really need this for a science project.

I'm trying to put this mod on my Minehut server and it wasn't working, I tried another mod to and it worked so I'm not sure if it's just this one

I'll put some pics so you can understand a bit better.

If you don't know as well, please just answer so I know.

Thank you and have a nice day! :)
