Can someone fix these two Open/Close Frame scripts?

function open()
if script.Parent.Text == "Options" then
script.Parent.Parent.OptionFrame.Visible = true
script.Parent.Text = "Close"
end
end

script.Parent.MouseButton1Down:connect(open)

This is the open script, that seems to be working, but for some reason the close (below) is not.

function close()
if script.Parent.Text == "Close" then
script.Parent.Parent.OptionFrame.Visible = false
script.Parent.Text = "Options"
end
end

script.Parent.MouseButton1Down:connect(close)

Can someone help me?

What does the output say?
