Why isnt my pause and play script not working?

stop = true
play = false




script.Parent.ClickDetector.MouseClick:Connect(function()
    if stop then
        stop = false
        if play == false then
            script.Parent.music:Resume()
            wait()
        end
        play = true
    else
        play = false
        script.Parent.music:Pause()
        wait()
    end
        stop = true
end)

The script seemed to have been working fine, and all of a sudden stopped working. I may have just deleted something without realizing, any help would be greatly appreciated.
