Why is this script for Shop Button not Working?

So, I made a LocalScript inside of an ImageButton that takes away from a value inside of a separate GUI and clones an item from Lighting and into a the clicker's backpack, but it doesn't seem to be working. I also cannot found any errors, so I was wondering if anyone could find something that I may have overlooked or screwed up on. Thanks for your time!

local money = game.Players.LocalPlayer.PlayerGui.MoneyGui.Frame.Amount.Money.Value
local price = 5

script.Parent.MouseButton1Click:connect(function()
	if money >= price then
		money = money-5
		local water = game.Lighting.Water:Clone()
		water.Parent = game.Players.LocalPlayer.Backpack
		print(game.Players.LocalPlayer.Name .. "has just bought Water!")
	end
end)

#1, Try putting water in ReplicatedStorage.

#2, Change how you define money by getting rid of the .Value at the end

Using Lighting to store items is a bad idea and just isn't used anymore. You also can't use .Value when defining Variables. This is just how Roblox Lua works. The resulting code after moving water to ReplicatedStorage and Changing how you define money would look something like this,

local money = game.Players.LocalPlayer.PlayerGui:WaitForChild("MoneyGui"):WaitForChild("Frame"):WaitForChild("Amount"):WaitForChild("Money")  --Remove.Value and add some Waits
local price = 5

script.Parent.MouseButton1Down:connect(function()
    if money.Value >= price then --Use .Value when refurring to the variable's value
        money.Value = money - price
        local water = game.ReplicatedStorage.Water:Clone() --Move water to replicated storage
        water.Parent = game.Players.LocalPlayer.Backpack
        print(game.Players.LocalPlayer.Name .. "has just bought Water!")
    end
end)

That should work. Good Luck!
