hello,  
i am new to flash and i confused. Like if i have an instance of an mc called NavBT which is inside a button. now on the button actions can i put this code:  
on (rollOver) {  
this.NavBt.gotoAndPlay(“lb-over”);  
}

so that when i rollover the button it goes and plays the label called lb-over which is inside the NavBT?

Thanks
