Seems easy.. but what have I done wrong here?

If this is a repost *Sorry!* OK, I'm learning java and reading a book on it, by the time I get a reply to this the problem may be solved BUT here goes.. This is just a simple Applet that draws out a 160x160 RED/BLACK checkerboard. However my problem is that I run it on the web page and it just comes up blank(gray). See if you can tell me why this isn't working or what I could do to fix it :) thanks The source is: import java.applet.*; public class CheckerBoard extends Applet { public void paint(Graphics g) { int yIn; // The distance from left int xIn; // The distance from top int width; // Width of square to draw int height; // Height of square to draw yIn = 0; xIn = 0; width = 20; //* Static Values height = 20; //* while ( yIn <= 160 && xIn <= 160 ) { if ( xIn == 0 || xIn == 40 || xIn == 80 || xIn ==120 ) { for ( yIn = 0 ; yIn <= 160 ; yIn += 20 ) { g.setColor(Color.red); // Start RED g.fillRect(xIn , yIn , width, height); // Draw RED yIn += 20; // Move R20 g.setColor(Color.black); // Start BLK g.fillRect(xIn , yIn, width, height); // Draw BLK } } // end if else { for ( yIn = 0; yIn <= 160 ; yIn += 20 ) { g.setColor(Color.black); // Start BLACK g.fillRect(xIn, yIn, width, height); // Draw BLK yIn += 20; // Move Rt. 20 g.setColor(Color.red); // Start RED g.fillRect(xIn, yIn, width, height); // Draw RED } } //end else xIn +=20; }//end Parent While } //end paint(Graphics)
