Script Works in Studio Mode But Not in Online Mode?

My script works 100% how it should in studio but when i test it in online mode, the deposit and withdraw functions dont work how they should. Everything eles works fine. 2 Scripts are used, ATM_Engine and Interest.

ATM_Engine Script

wait(15)
amount = game.ServerStorage.ATMStorage.Amount.Value
cash1 = game.ServerStorage.ATMStorage.CashInBank.Value
cashvalue = script.Parent.Screen.SurfaceGui.CashValue1
cashvaluehold = 0
function click1()
	if amount == 0 then
		amount = amount + 1
	else
		amount = amount * 10
		amount = amount + 1
	end
end
function click2()
	if amount == 0 then
		amount = amount + 2
	else

		amount = amount + 2
	end
end
function click3()

The main aim of these scripts are too allow the used to deposit money from the server storage into the "ATM" and it gains interest before allow them to take it out again. Only started scripting 8 days ago and wanted to create this as my first project.

Try making your script a LocalScript. it still doesn't work, please just include the bit that's erroring.

game.Players.LocalPlayer does not work to find the player...

local plr = script.Parent.Parent.Parent.Parent.Parent.Parent.Parent
plrn = script.Parent.Parent.Parent.Parent.Parent.Parent.Parent.Name

is how I found the player and player name. this works if clicked on a click detector.

localplayer is not actually the player.
