Why isn't my script working?

[OliDevsRBLX]

@SOTR654

function format(Id)
	return string.format("rbxthumb://type=Asset&id=%s&w=420&h=420", Id)
end

while wait(30) do
	script.Parent.Decal1.Texture = format(6881965865)
	script.Parent.Decal2.Texture = format(6881965865)
	wait(30)
	script.Parent.Decal1.Texture = format(6897736901)
	script.Parent.Decal2.Texture = format(6897736901)
	wait(30)
	script.Parent.Decal1.Texture = format(6881965865)
	script.Parent.Decal2.Texture = format(6881965865)
	wait(30)
	script.Parent.Decal1.Texture = format(6897736901)
	script.Parent.Decal2.Texture = format(6897736901)
end

That works! Thanks a lot!
