Loading external text-file, works, but still get an error message, why?

so, i made a layer called text, with a dynamic textfield and called the instance “newsText”. and then wrote the following ascript on a new layer;

myText = new LoadVars();
myText.onLoad = function();

MyText {
newsText.text = this.myVariable;
}

myText.load(“newstext.txt”);

i manage to load the text, but i got the following mesage, and i don´t understand why it complains about “Ext_text” and “test.txt” since I changed it to “myText” and “newstext.txt” :-/

Error Symbol=newstext bar 1, layer=newsbar, frame=1:Line 1: Statement must appear within on/onClipEvent handler
Ext_text = new LoadVars();

Error Symbol=newstext bar 1, layer=newsbar, frame=1:Line 2: Statement must appear within on/onClipEvent handler
Ext_text.onLoad = addText;

Error Symbol=newstext bar 1, layer=newsbar, frame=1:Line 3: Statement must appear within on/onClipEvent handler
Ext_text.load(“test.txt”);

Error Symbol=newstext bar 1, layer=newsbar, frame=1:Line 4: Statement must appear within on/onClipEvent handler
function addText() {
