Other waves dont load And the script doesn't transform??

The problem is That My script won't load fully it only Loads the rotate mesh that spins And it doesn't load the rest Of the other Mesh and breaks the The whole script Here

This is the Error Im getting :27: attempt to index field 'Parent' (a nil value)

27:line ----> wm31.Parent.CFrame = wm31.Parent.CFrame * CFrame.fromEulerAnglesXYZ(0,0.5,0)
