Loading external text

Hi all.
I got a question.
I have correct .txt file, which contains 2 vars (Nederlands and Engels.

[SIZE=“2”]this.loadVariables(“introtext.txt”);
this.onEnterFrame = function() {
this.introText.text = this.Nederlands;

};
//not working part
this.btnUk.onPress = function() {
this.onData = function() {
this.introText.text = this.Engels;
};
};[/SIZE]

So as you can can see, i want a btn which one will replace the ‘Nederlands’ var text with the ‘Engels’ var text. But that doesn’t work!
thanks in advance.
