Flash 8 how to change loadVar via instance name

Hi there, its been a while since I’ve scripted so I’m very rusty. Can someone please point me in the right direction on how to go about the following?

I have an mc with a dynamic text box inside with script that loads in different txt files dependant on the instance name of the mc. What i’d like to do is have all the different txt files combined into one txt file and then have the code open up which ever section is needed. I didn’t want to duplicate the mc unnecessarily so thought the best way was via the instance name to define which section it opens but am open to suggestions…

I’m not sure on where to begin so if this is an array thing or something else i don’t mind do the research i just don’t know where to start!

So far I have been using the following code:

textName = this._name;

var format = new TextField.StyleSheet();
var path = “css/flash.css”;

format.load(path);
format.onLoad = function(success) {
if (success) {
output.styleSheet = format;

myLoadVar = new LoadVars();
myLoadVar.load(“text/”+textName+".txt")
myLoadVar.onLoad = function (success) {
if (success == true) {

       //  I'd like to change the following line so that 'changeThis' 
       //  can be changed via the mc instance name

output.htmlText=myLoadVar.changeThis;

}
}

} else {
output.text = “Error loading CSS file!”;
}
}
