AS3 looping help

Question

This can't be too difficult but I can't seem to figure it out. Could someone please tell me how to loop this motion.
I have added some action script to horizontally animate a strip of text... now I need that to loop so it's continuous.
this is my code
countries_mc.addEventListener(Event.ENTER_FRAME, fl_AnimateHorizontally);
function fl_AnimateHorizontally(event:Event)
    countries_mc.x -= 2;
thanks

It does work and I have tweeked it a bit but the loop doesn't work when you make it go in the opposite direction.
Here's the code
countries_mc.addEventListener(
Event.ENTER_FRAME, fl_AnimateHorizontally); 
//moving _mc from right to left-this works perfectly
function fl_AnimateHorizontally(event:Event)
    countries_mc.x+= 5;
     if (countries_mc.x > stage.stageWidth){               countries_mc.x=-520;      }
} //moving movie clip from left to right?-i cant get this part to work
text_mc.addEventListener(Event.ENTER_FRAME, fl_AnimateHorizontally2);
 function fl_AnimateHorizontally2(event:Event)
    text_mc.x+=-5;      if (text_mc.x > stage.stageWidth){               text_mc.x=0;      }
