I can't get this simple script to work I'm such a noob?

script.Parent.MouseButton1Down:Connect(function()
	local music = script.Parent.Parent.Parent.Parent.Parent.PlayerScripts.LocalBackgroundMusic:WaitForChild("BGM")
		if music.Volume > 0.7 then
		music.Volume = 0
		script.Parent.Text = "Unmute Music"
		elseif music.Volume < 0.7 then
			music.Volume = 0.7
			script.Parent.Text = "Mute Music"
		end
end)

If the volume is 0.7, nothing will happen.

script.Parent.MouseButton1Down:Connect(function()
    local music = script.Parent.Parent.Parent.Parent.Parent.PlayerScripts.LocalBackgroundMusic:WaitForChild("BGM")
        if music.Volume >= 0.7 then
        music.Volume = 0
        script.Parent.Text = "Unmute Music"
        else
            music.Volume = 0.7
            script.Parent.Text = "Mute Music"
        end
end)

This checks whether the volume is bigger than or equal to 0.7, but the original only does stuff when the volume is bigger than 0.7.
