scrolling text field help as3

Currently got text off stage that I would like to come onto the stage and stop at a certain position (97, 233.10) on my stage. I'm a little confused on where to stop it and what code to use?

addEventListener(Event.ENTER_FRAME, mcInfo);

 function mcInfo (e:Event):void {

//check position of logo
//if inside the stage move left to right
//if outside stage reposition

if (info.x<stage.stageWidth) {
    info.x+=30;
    stop();
    } else {
        //reset position
        info.x=-450;
    }
}

Cheers!

It also seems that Flash is now returning an output error when I scroll through the rest of my pages:

TypeError: Error #1009: Cannot access a property or method of a null object reference.

In the if statement we check if the object has exceeded the target position and stop the loop if it has. Otherwise keep incrementing the object's position.

targetPosition = {x:97, y:233.10};

addEventListener(Event.ENTER_FRAME, mcInfo);

function mcInfo(e:Event) {
   if (info.x >= targetPosition.x) {
      info.x = targetPosition.x;
      removeEventListener(Event.ENTER_FRAME, mcInfo);
   } else {
      info.x += 30;
   }
}
