I can't make a script button that when you click the button it change the color of the flashlight ?

My script w'ont stop buying when i have already clicked and buy the color

local plr = game.Players.LocalPlayer
local char = plr.Character	

Buyed = false
IsNotBuy = false

script.Parent.MouseButton1Click:Connect(function()
	Buyed = true
	if Buyed == true then
		local flashlight = char.HumanoidRootPart:WaitForChild("player_flashlight")
		flashlight.Color = Color3.fromRGB(255,0,0)
		game.ReplicatedStorage.Click:Play()
		if IsNotBuy == false then
			plr.Leaderstats.OriCash.Value = plr.Leaderstats.OriCash.Value - 1700
			IsNotBuy = true
		end
		Buyed = false
	end
	
end)
