Problems with loading in swf files

programming flash
1

im trying to load in a different swf file depending on which key the users pressed, but i can only ever load one in before having to quit.

heres my code:


onClipEvent(enterFrame) {
	if( Key.isDown(49) ) {
		this.unloadMovie()
		this.loadMovie( "Sanyo-3DmapSim scene01.swf" )
	}
	if( Key.isDown(50) ) {
		this.unloadMovie()
		this.loadMovie( "Sanyo-3DmapSim scene02.swf" )
	}
	if( Key.isDown(51) ) {
		this.unloadMovie()
		this.loadMovie( "Sanyo-3DmapSim scene03.swf" )
	}
	if( Key.isDown(52) ) {
		this.unloadMovie()
		this.loadMovie( "Sanyo-3DmapSim scene04.swf" )
	}
	if( Key.isDown(53) ) {
		this.unloadMovie()
		this.loadMovie( "Sanyo-3DmapSim scene05.swf" )
	}
}

this is on a movieclip on my main timeline. is that the problem, should i be creating an empty MC everytime i load a swf then destroy it before loading the next one??

Any help would be great
