Why wont the clicks come through?

I tried to alter a script where when u click you get 1 click, but with 50 coins you can buy 1.5x clicks. Here is my script:

local button = script.Parent
local player = button:FindFirstAncestorOfClass("Player")
repeat
	player = button:FindFirstAncestorOfClass("Player")
	task.wait()
until player ~= nil

local debounce = true
button.MouseButton1Click:Connect(function()
	if debounce then -- if debounce is true
		debounce = false

		local leaderstats = player:WaitForChild("leaderstats")
		local Clicks = leaderstats:WaitForChild("Clicks")
		Clicks.Value += 1
		
		if game.StarterGui.Shop.ShopFrame.X1dot5.MouseButton1Click then -- here is what I add and it does not work
			if game.Players.LocalPlayer.leaderstats.Coins.Value == 50 then
				Clicks.Value +=0.5
			end
		end
				
			
		
		
		
		
		

		task.delay(0.5, function() -- after 1 second, debounce will turn true
			debounce = true
		end)
	end
end)

Thanks for helping!

first on line 2 you can do:

local player = game:GetService("Players").LocalPlayer

It works better and is more reliable. the repeat loop from line 3 to 6 can go, player is already defined and looping something over it is worthless.

to solve the actual issue you asked about try this:

on line 19 instead of:

Clicks.Value +=0.5

do:

Clicks.Value *=1.5

changing the + symbol to a * makes it multiply instead. we change 0.5 to 1.5 because otherwise you lose clicks.
