perhaps elsewhere in your program something is trying to access one of the
arrays at element[0], which would be null.

run your applet - when the npe is generated, open the java console and you
should see which line number is generating the error.

try taking everything back to 0-based, and see if you still get the npe

for (int h = 0 ; h < panel.length ; h++ )
{
  System.out.println(h);
  panel[h] = new Panel();
  panel[h].setLayout(new GridLayout(0,1));
  for (int v = 0; v < txt.length ; v++ )
  {
    txt[v] = new TextField(1);
    System.out.print(v);
    panel[h].add(txt[v]);
  }
  add(panel[h]);
}

Or you didn't initialize the array?

panel = new Panel[numberOfPanels];

Anyway, this isn't Swing specific - moving to Java in General (beginner)...
