Set text size to auto using javascript

[BrianZebra]

Hello!  I just thought I would post this as I have been trying to figure out how to set the text size to auto using javascript.  What finally worked  was setting the text size to ""  Posting it just in case someone else is searching for the same thing.

this.getField(fName).textSize = "";

The value of this property is a number. Use the value 0 for Auto.
