loading an external swf

I can do this with a button ok eg:

on(release){
menuload.loadMovie("menufinal.swf");
}

this loads into the empty mc and works great. But I want to to happen auotmatically when it enters frame 4. So nobody has to click anything- it just loads.

I can't seem to work out how to do this.

Would be very appreciative of help
:confused:

Add a "KeyFrame" to frame 4 and in the ActionScript add the following
menuload.loadMovie("menufinal.swf");

cheers mate - Doh!
