I am very new to AS3, so I cannot for the life of me figure out how to return a value out of a ROLL\_OVER function. It seems extremely easy, yet I cannot get it to work. Here is a simplified version of what I am trying to do:

test\_mc.addEventListener(MouseEvent.ROLL\_OVER, testOver);

function testOver(event:MouseEvent):String  
{  
return “hello”;  
}

trace(testOver());
