button down with external content

I'm trying to find a way of keeping a mc button on the last
frame of it's timeline i.e. down the problem being the buttons
function is to load an external swf into a container on the _root
timeline. I cannot work out how to do this without messing the code
for the button up. Here is the code for one button. Any help
appreciated!



stop();



this.onEnterFrame = function(){

if(rewind == true){

prevFrame();

}

}



this.onRollOver = function(){

rewind = false;

play();

}



this.onRollOut = function(){

rewind = true;



}



this.onPress = function() {

if (_root.currMovie == undefined) {

_root.currMovie = ''weather'';

_root.container.loadMovie(''weather.swf'');

} else if (_root.currMovie != ''weather'') {

if
(_root.container._currentframe%26gt;=_root.container.midframe) {

_root.currMovie = ''weather'';

_root.container.play();

}

}

};
