Load dynamic text file - reads UNDEFINED

[visualizer03]

Attached is a fla file and txt document.

I am trying to dynamically load a txt document into the agenda scene of this document. It works sporadically. The goal is that a non-savvy computer user can update the flash presentation with his/her agenda without ever opening or having to touch flash.

This is the code I am using in flash:

stop();

myData = new LoadVars();
myData.onLoad = function()
{
myText_txt.html=true;
myText_txt.htmlText = this.myVariable;
};
myData.load("myText1.txt");


However, when I edit the txt file and resave the flash swf reads "undefined" rather than the displaying the updated agenda.

Any suggestions? What did I miss?
