I think there is a larger issue...
you are putting code on a movieclip... which is a very bad idea... put the code on the main timeline... preferably in the very first frame of the top layer.
but from your code, I can see you are using AS 3.0 and from what I can tell, you are not able to reference a movieclip this way anymore.
I even tried placing the dynamic text field in a movieclip first and tried using trace(parent.textBox_mc.myText_txt.text); and I got an error. if you change the ActopmScro[t version to 2.0, you don't have an issue...
so your options are...
- don't use AS 3.0 which i would NOT recommend
- only put your code in one spot and reference everything correction.
