Dynamic text fields help

hi everyone am creating a dictionary of my javascripts on Flash MX am doin great creating it, i have on the stage a combo box that has the codes and am using it to load my variables threw it, i have two dynamic text fields that displays the data on one i have the codes and on the other i want to load the esplanation of what the codes does. Here is where i ran into a little problem.

here is the question: how do i load two separated files with the same loadVariables command. i hope i make sense. here i post a couple of codes.

myData = new LoadVars();
myData.load(“codes.txt”);
//creating the loadVarsText function

[color=Red]selectedindex = _root.codes.getSelectedIndex();[/color]//this is my combo box i used the getSelectedIndex() to retreave a number Index from the combo. this number i used it to get the variable store in text file. now i need to know how to make so that i could load two different variables to load from different text files to display the two files in the two text fields.

myData.onLoad = function() {
if(selectedindex == 0){
_root.displayArea.text = this.code1;
}
if(selectedindex == 1){
_root.displayArea.text = this.code2;
}
if(selectedindex == 2){
_root.displayArea.text = this.code3;
}
if(selectedindex == 3){
_root.displayArea.text = this.code4;
}
if(selectedindex == 4){
_root.displayArea.text = this.code5;
}
if(selectedindex == 5){
_root.displayArea.text = this.code6;
}
if(selectedindex == 6){
_root.displayArea.text = this.code7;
}
if(selectedindex == 7){
_root.displayArea.text = this.code8;
}
if(selectedindex == 8){
_root.displayArea.text = this.code9;
}
if(selectedindex == 9){
_root.displayArea.text = this.code10;
}
if(selectedindex == 10){
_root.displayArea.text = this.code11;
}
if(selectedindex == 11){
_root.displayArea.text = this.code12;
}
if(selectedindex == 12){
_root.displayArea.text = this.code13;
}
if(selectedindex == 13){
_root.displayArea.text = this.code14;
}
if(selectedindex == 14){
_root.displayArea.text = this.code15;
}

};
}
