Why won't my spell script work?

This is why tabbing your code correctly is very important.

Every time you start a block, increase your tabbing (with one tab). The ROBLOX script editor tries to help out with this.

Every time you stop a block, decrease your tabbing (and add the appropriate end [or until for repeat]).

If we tab your code, we get this:

bin = script.Parent
me = script.Parent.Parent.Parent

enabled = true
function Talk(msg)
	game:GetService("Chat"):Chat(me.Character.Head, msg, Enum.ChatColor.Red)
end

function KeyDown(key)
	if key == "z" then
		if not enabled then
			return
		end

		local player = game.Players.LocalPlayer
		if player == nil then
			return
		end
		--Here is how i disabled the tool from working after you click once "enabled = false"

		enabled = false
		LeftShoulder = me.Character.Torso["Left Shoulder"]
		RightShoulder = me.Character.Torso["Right Shoulder"]
		Neck = me.Character.Torso["Neck"]
		value1 = LeftShoulder.C0
		value2 = RightShoulder.C0
		value3 = Neck.C0


		Run = game:GetService("RunService")

		RightShoulder.C0 = RightShoulder.C0 *CFrame.Angles(-0.5, 0, 0)
		LeftShoulder.C0 = LeftShoulder.C0 *CFrame.Angles(-0.5, 0, 0)

		wait(0.75)
		Neck.C0 = value3
		RightShoulder.C0 = value2
		LeftShoulder.C0 = value1
		wait()
		RightShoulder.C0 = RightShoulder.C0 *CFrame.Angles(0, 0, 1.5)
		LeftShoulder.C0 = LeftShoulder.C0 *CFrame.Angles(0, 0, -1.5)

		Talk("Air Blast!")

	enabled = true
	function onS(key) 
		key.KeyDown:connect(function() onKeyDown(key) end) 
	end 
	bin.Selected:connect(onS)

Notice how when we get to the end, it's still "floating" away from the left. That means we missed an end somewhere.

I'm guessing the end should go before that final enabled = true line (and that line should probably be deleted) -- it doesn't make sense to put functions in functions, especially since that one calls the one above it!

Thus the end of your script would look like

		....
		wait(0.25)
		--Heres how long you want it to be before you use it again change wait(2) to anything u want

		wait(4)
		--Here is how i made it able to work again after the time has run out "enabled = true"
		enabled = true
	end
end

function onS(key) 
	key.KeyDown:connect(function() onKeyDown(key) end) 
end 
bin.Selected:connect(onS)

Beyond that, there are other problems.

• Your function is named KeyDown, but your event calls onKeyDown.

• You define variables (e.g., LeftShoulder) but don't make them local. You should always make variables local when it works (e.g., doesn't work for enabled -- that one belongs as a global)

• ROBLOX encourages :FindFirstChild instead of :findFirstChild.

• You can just compare character objects instead of their names: if c ~= me.Character

• It isn't possible for LocalPlayer to be nil when you're using a LocalScript.

• You defined Run inside of the function (it should belong at the top, since it doesn't change depending on when the function is run) but never use it

• You use bad variable names like zomg

• The thing for choosing brick color should probably just use else.

• If the first argument to math.random is 1, you can just drop it! math.random(1, 2) is the same as math.random(2)

Because you don't have the right number of ends
