Why does this not work?

 local cd = script.Parent

function onclick(Player)
print("PassedTheFunction")
if Player.PlayerGui:FindFirstChild("BoomGui") == nil and game.Workspace:FindFirstChild("LocalSoundForBoomBox") == nil then
	print("les get it started in ere")
	game.ReplicatedStorage.BoomGUI:Clone().Parent = Player.PlayerGui
    print("It should give it to us!")
end
end

cd.MouseClick:connect(onclick)

The script runs, I see all of the prints in the output, no errors in the output, doesn't give the the "BoomGUI". Please help.

Make local cd = script.Parent to cd = script.Parent

make it a local function

 local cd = script.Parent

local function onclick(Player)
print("PassedTheFunction")
if Player.PlayerGui:FindFirstChild("BoomGui") == nil and game.Workspace:FindFirstChild("LocalSoundForBoomBox") == nil then
    print("les get it started in ere")
    game.ReplicatedStorage.BoomGUI:Clone().Parent = Player.PlayerGui
    print("It should give it to us!")
end
end

cd.MouseClick:connect(onclick)

Nothing wrong with it lol

 local cd = script.Parent

function onclick(Player)
print("PassedTheFunction")
if Player.PlayerGui:FindFirstChild("BoomGui") == nil and game.Workspace:FindFirstChild("LocalSoundForBoomBox") == nil then
    print("les get it started in ere")
    game.ReplicatedStorage.BoomGUI:clone().Parent = Player.PlayerGui --clone() not Clone()
    print("It should give it to us!")
end
end

cd.MouseClick:connect(onclick)
