Problem loading variable from external file

1

hi

i have this code:
var loadText = new loadVars();
loadText.onLoad = function(success) {
if (success) {
myVar = this.myVar;
trace(myVar);
loadMovie(myVar add “.swf”, _root.container_mc);
} else {
trace(“Error loading data”);
}
};
loadText.load(“data.txt”);

to load an external variable to load one movie, on the data.txt I have myVar=video1

my problem is that he is not loading video1.swf to container mc, but the trace to the cvariable name is correct

can someone give me a clue?

thanks
