How do I make it so this script also detects if you got the wrong pattern?

local Player = game.Players.LocalPlayer
local door = game.Workspace.Ending.Door
local Parts = {
["Part1"] = 1;  
["Part2"] = 2;
["Part3"] = 3;
["Part4"] = 4;  
}
local Part1 = game.Workspace.Ending.Black
local Part2 = game.Workspace.Ending.Teal
local Part3 = game.Workspace.Ending.Purple
local Part4 = game.Workspace.Ending.Red
local num = 0
local tries = 0

local fail = function()
	tries = 0
	print("Wrong pattern")
end

Part1.ClickDetector.MouseClick:Connect(function()
    local target = num+1
    if Parts["Part1"] == target then
        num = num+1
    else
        num = 0
    end
	if tries < 3 then
		tries = tries+1
	else
		fail()
	end 
end)

Part2.ClickDetector.MouseClick:Connect(function()
    local target = num+1
    if Parts["Part2"] == target then
        num = num+1
    else
        num = 0
    end
	if tries < 3 then
		tries = tries+1
	else
		fail()
	end  
end)

Part3.ClickDetector.MouseClick:Connect(function()
    local target = num+1
    if Parts["Part3"] == target then
        num = num+1
    else
        num = 0
    end
	if tries < 3 then
		tries = tries+1
	else
		fail()
	end  
end)

Part4.ClickDetector.MouseClick:Connect(function()
    local target = num+1
    if Parts["Part4"] == target then
        num = 0
        door.Transparency = 1
        door.CanCollide = false
		tries = 0
    else
        num = 0
    end
	if tries < 3 then
		tries = tries+1
	else
		fail()
	end  
end)
