Applet not running java

Question

I'm wondering why my applet isn't running. I'm using netbeans, and the program works fine with no errors, but I can't seem to get the applet screen to appear to test all the functions of my program.I was wondering if someone can point out what I am doing wrong in starting my applet up. I haven't done to many things with applets, so I'm quite curious why it isn't upping and running for me. I really didn't want to post the full code of my program, but I've no idea if there's an error in my code, or I'm just not doing the right thing to actually start the applet or something.

I do not get any errors while running my program, that applet simply does not appear and run in itself. Otherwise I get no errors from neatbeans while running my program.
