The "then" of an if statement is optional, so that has no bearing. I was referring to the msg variable holding an invalid values, so something like this may be required:


msg = wait(0, screen.GetMessagePort())
if msg<>invalid then
    if msg.isScreenClosed() then

    else if msg.isButtonPressed()

    end if
end if
