createTextField twice on one movieclip not working [AS 2.0]

I have a movieclip that I’m trying to attach two textfields to. Here’s my current code:

_root.createEmptyMovieClip("showGrowthOver1",_root.getNextHighestDepth());
showGrowthOver1._x = 10;
showGrowthOver1._y = 550;
showGrowthOver1.createTextField("label_txt",_root.getNextHighestDepth(),0,0,200,20);
showGrowthOver1.createTextField("input_txt",_root.getNextHighestDepth(),210,0,100,20);
showGrowthOver1.input_txt.type = "input";
showGrowthOver1.input_txt.text = "1";
showGrowthOver1.label_txt.text = "Highlight Growth Greater than 1";

As it is, only the “input_txt” field appears. If I comment out the line that creates the “input_txt” field, then the other one appears. I can’t get them both to appear at the same time. Am I not allowed to include two textboxes like this or am I doing something else wrong?
