This is what I have right now: script.Parent.Parent.Main.Main.BackgroundColor3 = Color3.fromRGB(209, 209, 209)
For some reason, it doesn't work and I have no idea how to fix it.
That code is correct actually, you probably have the wrong code for the "script.Parent.Parent.Main.Main" and you should add WaitForChild's instead because sometimes the script looks for the TextLabel before everything loads in.
