Hey everyone,

I have a quick newbie question for you, as I am not a programmer.  
I want to autoSize my text field.

I have a text scrollbar module. Text is coming from an XML file and I simply want the text field to autoSize itself, according to the XML text length. Allowing me to feed infinite text into it.

Structure: [FONT=Arial]mc\_text \> contentMC \> tText[/FONT]

“mc\_text” is the main MovieClip, which contains “contentMC” and inside that you find the text field “tText” that needs to be autoSized.

[FONT=Arial]Instance names:[/FONT]

[FONT=Arial]scroller’s track: scRollBarMC[/FONT]  
[FONT=Arial]scroller’s slider: scrollBar[/FONT]  
[FONT=Arial]text field mask: mask[/FONT]

[FONT=Arial]I found the autoSize code already, but i don’t know how to apply it, where to put it etc, so please paste the proper code into my script and copy the corresponding chunk into your answer, if you can.

[FONT=Arial]If you have any questions let me know, thanks!
