Action Script 'Define' and 'Statment' errors

Hey Folks

Trying to load a movie [swf] on top of my main flash page and I get these errors…


Error Symbol=page4, layer=Layer 10, frame=1:Line 1: Statement must appear within on/onClipEvent handler
videogbutton.onPress = function() {


It’s a movie clip as a link on one of the pages that has a script attached to it as follows

videogbutton.onPress = function() {
loadMovieNum(“videog.swf”, 1);
};

Also I added the instance name videogbutton to that movie clip

Results:

The movie loaded successfully on top of my main page but with those errors.

Any help appreciated.

BTW Newbie here.

Thanks
