Load text in external swf from main.swf

Hi
I’m trying to load a external txt into a swf which is loaded in main.swf .
In the text.swf standalone the text appears, but once loaded into main.swf the text doesn’t work anymore.

text.fla includes a MC which is used to load the txt for scrolling

onClipEvent (enterFrame) {
	if (down == "1") {
		this.textField.scroll += 1;
	}
}
onClipEvent (enterFrame) {
	if (up == "1") {
		this.textField.scroll -= 1;
	}
}

the buttons used to load external txt use this

on (press) {
	loadVariables("/texts/general.txt", "_root.text_box");
}

I think the problem is with “_root.text_box” in any way, just don’t know how.

any help is apreciated

the MC is called textBox
