Looks like Jim answered this for you already. As he said, you cannot reference the controls before the form is run because they don't exist until the form exists. Passing a parameter to the INIT() method allows you to set the desired enabled/disabled state of the controls before the form becomes visible to the user, which accomplishes what you want from the user's point of view.
