(Better Reupload) Used to work but now no longer works and I don't know why?

Edit: Earlier I did not provide the script now I will so you guys can help me with a solution

I don't know a lot about code and when I created something that no longer works, it makes me paranoid that I can't fix it and it can happen to my other codes. These are two scripts in one part doing different things at the same time. The two scripts I made were confirmed to be working fine from another question but despite that, the part still doesn't work becaus3e the part doesn't even become visible.

First script

while true do
	script.Parent.CFrame = script.Parent.CFrame * 			CFrame.fromEulerAnglesXYZ(0,0.1,0)
	wait()
end

Second script:

wait(3)
script.Parent.Transparency = 0
