onMotionFinished problems... Im sure its simple

If you look at my .fla file you’ll see what I am trying to do, I am trying to create a small app that shows scrolling data from an XML file. I want to tween the TextBox’s that are all grouped within text_mc.

For some reason though I cant find a way to tween the second movement of the text box’s only the initial movement when it comes on the page. I think it has something to do with the 2nd time onMotionFinished is processed. The Tween never seems to begin.

Please take a look at my flash file for a better understanding,… Any help will be greatly appreciated
