Why is my Image Label Rotation Script dying out???

So i had this Local Script in my GUIthat is suppose to make an image label spin, It used to work flawlessly but now, after an update it works and then stops working after a few seconds entirely...even if i *disabled *and *enabled *the script wont work. It is like the script literally just dies out.

while true do
wait()
----------------
for i = 1,200 do        
    wait()
    script.Parent.Rotation = script.Parent.Rotation + 10
    end
script.Parent.Rotation =  0
end
