you might have an issue with using x as a global variable? try defining
x with "var" in the for loop.. or somewhere in the function. if you do
not use var, it should become a global variable.

Re: [Flashcoders] random concatenated txt question
I don't see anything there in that code that limits the string length to
19, nor anything to reset the string to a null value upon reaching the 19.
It just keeps on concatenating onto the end of the string, but you can't
see it because of the limited size of the textfield.
Try putting a trace in your onEnterFrame() and you'll see what I mean:
_root.onEnterFrame = function() {
myTxt_txt.text = random2();
trace("myTxt_txt.text: "+myTxt_txt.text.length)
};
That said, it seems to me that you're really going about this the hard
way. Each of those single-letter strings is possible to represent with a
numeric ascii value, such that there is no need for the array -- just
convert the chosen numeric value to a character at the time it is
concatenated.
