Calling a function from a function

How can I get a function to call another function? I simply cannot get it to work:


function displayMenu() {
clearMenu
}

This is a cut down version of my code for clarification purposes - it doesn’t work either.

Does it have to be in an “on” handler (onClipEvent or onEnterFrame for example)? 'cause I just want it to run the other function automatically without the user having to do anything or the movie having to go to any particular frame. blah
