nextScene() is not working

i have button and i have this code

on(press)
{
if (tunnellength.text == "" || highintensity.text == "" || lowintensity.text == "")
{
this.createEmptyMovieClip("err",this.getNextHighes tDepth());
err.attachMovie("erro","err",this.getNextHighestDe pth());
}
else
{
trace("to the scene 2");
trace(nextScene());
}
}


but it doesnt go to next scene even if the condition is correct

it traces as undefined
