Mouse not showing up when clicked on the buttons ?

This is a cut script from my shop GUI, cuz i don't want to post long scripts here, also people from stealing it..

At line 10, line 16, line 23 i'm trying to set where the player's mouse is make text appear once he clicks.

Printing shows up in the output, but the text doesn't work at all if i remove the UDim2.new(0, mouse.X, 0, mouse.Y) lines for all of them it will work but thats not what i want.

local Player = game.Players.LocalPlayer
local mouse = Player:GetMouse()

function BuyArmor(armor, price)
	if Player.UnlockedArmor:FindFirstChild(armor).Value == false then
		if Player.leaderstats.Gold.Value >= price then
			Player.leaderstats.Gold.Value = Player.leaderstats.Gold.Value - price
			Player.UnlockedArmor:FindFirstChild(armor).Value = true
			print("bought")
			bought.Position = UDim2.new(0, mouse.X, 0, mouse.Y) -- <
			bought.Visible = true
			wait(1.5)
			bought.Visible = false
		else
			print("not enough")			
			notenough.Position = UDim2.new(0, mouse.X, 0, mouse.Y) -- <
			notenough.Visible = true
			wait(1.5)
			notenough.Visible = false
		end
	else
		print("already got armor")		
		alreadyhave.Position = UDim2.new(0, mouse.X, 0, mouse.Y) -- <
		alreadyhave.Visible = true
		wait(1.5)
		alreadyhave.Visible = false	
	end
end

for i = 1, #buttons do
	GUI.Hold.Frame1:FindFirstChild(buttons[i]).MouseButton1Click:connect(function() BuyArmor(armorVarNames[i], prices[i])end)
