AngelCodeFont problem (slick2d)

I’m trying to use a AngleCodeFont by loading it like so:

resultsFont1 = new AngelCodeFont("data/fonts/quartzms.fnt","data/fonts/quartzms.png");

But then when I set the font to that and draw a string nothing shows up. Any idea why?

Just use it like images. But drawString except draw.

resulFont1.drawString(float x, float y,  java.lang.String text);
