This script works only in studio but not in the actual game, how do i fix that?

Here's the script:

wait()
Player = script.Parent.Parent.Parent.Parent.Parent.Parent.Parent
Strength = Player.Data.Strength
AP = Player.Data.AP
Input = script.Parent.Parent.Input.Value
Enabled = true

script.Parent.MouseButton1Click:connect(function() 
	if Player.Data.AP.Value >= Input.Value and Enabled == true then
		Enabled = false 
        script.Click:Play()
        wait()
        AP.Value = AP.Value - Input.Value
        Strength.Value = Strength.Value + Input.Value
        wait(0.45)
        Enabled = true
    end
end)

P.S it's a local script inside a button inside a frame inside a gui inside a starter gui
