Url for txt file in dynamic text field?

programming flash

Hi, I have a problem with a dynamic text field, which displays a txt file.

If I hardcode the file name in the code, then it works fine. This is on the first frame of my movie, which holds the dynamic text field.

myData = new LoadVars();
myData.onLoad = function(success)
{
	if (success)
	{
		mytxt.htmlText = this.txt;
	}
};

myData.load("test.txt);

stop();

But if I try to define the url of the text with a variable, and try to send it the url in the browser (.swf?txturl=http://www.myurl.com/), it doesn’t work:

myData = new LoadVars();
myData.onLoad = function(success)
{
	if (success)
	{
		mytxt.htmlText = this.txt;
	}
};

link = _root.txturl + "test.txt";

myData.load(link);

stop();

Is there a trick to defining url’s for dynamic text fields? Because if I hardcode the path from the server, it works locally, but again not on the server…

Could it be a problem of permisson (since the url of the txt is from a different page than the one the swf is on)?

Any ideas? Thanks!
