GUI won't go visible, won't even print out an error, or "idk.."?

Hey, I'm making a game. A character selection basically, you can use the morphs options menu, with remove morph, and change morph. Let's focus on change morph. When I press it, it teleports the player to the kill part normally. It waits 7 seconds. After 7 seconds, it does absolutely nothing. No errors in the output, it won't even print out the print("idk..") I have in the script. Here it is.

local char = script.Parent.Parent.Parent.Parent.Parent.Character
script.Parent.MouseButton1Click:Connect(function()
    print("idk")
    char.HumanoidRootPart.CFrame = game.Workspace.killplayerpart.CFrame
    wait(7)
    script.Parent.Parent.Parent.Parent.ScreenGui.select.Visible = true
    print("idk..")
end)

Any working answer is appreciated! (It's a localscript)
