Enabled and Disabled - help please!

Hi all,

I have this movieclip with buttons residing in the main timeline. This movieclip is set with an _alpha = 0. How do I disabled this movieclip/buttons in the main timeline as well? The movieclip will be visible only if another button(not within this movieclip) is pressed.

I tried using the following but it doesn’t work.

movieclipInstanceName.enabled = false;

How do I go about doing it?

Thanks for any input in advance.
