Tween not playing, can someone help

So, i made a attack for my game, and the attack is basically a skull, which opens its mouth and a beam comes out, so i made a tween for that, and it doesnt seem to be working, does anyone know why

Here is the code:

Are you getting any exceptions?

Maybe you should try using orientation instead of cframe? The same thing happened to me when I tried rotating an object by tweening it’s cframe, for some reason it worked when I tweened its orientation instead. I haven’t the faintest clue why.

I found out why that was happening, it was still welded, which prohibited the object from moving.
