Conditional Statement Help Request

i have arduino esplora rev04 board. trying make controller 1 of games , use linear potentiometer item selector. have written series of loops intent of checking state , if has changed print new result if has changed

code: [select]


  int lp = esplora.readslider();
  int lp1;
  int lp2;

  if (lp > 918) lp1 = 1;
  if (lp < 917 && lp > 816 ) lp1 = 2;
  if (lp < 815 && lp > 714) lp1 = 3;
  if (lp < 713 && lp > 612) lp1 = 4;
  if (lp < 611 && lp > 510) lp1 = 5;
  if (lp < 509 && lp > 408) lp1 = 6;
  if (lp < 407 && lp > 306) lp1 = 7;
  if (lp < 305 && lp > 204) lp1 = 8;
  if (lp < 203 && lp > 102) lp1 = 9;
  if (lp < 101) lp1 = 10;

  if (lp1 != lp2 , lp1 == 1) { keyboard.write('1'); lp2 = lp1; };
  if (lp1 != lp2 , lp1 == 2) { keyboard.write('2'); lp2 = lp1; };
  if (lp1 != lp2 , lp1 == 3) { keyboard.write('3'); lp2 = lp1; };
  if (lp1 != lp2 , lp1 == 4) { keyboard.write('4'); lp2 = lp1; };
  if (lp1 != lp2 , lp1 == 5) { keyboard.write('5'); lp2 = lp1; };
  if (lp1 != lp2 , lp1 == 6) { keyboard.write('6'); lp2 = lp1; };
  if (lp1 != lp2 , lp1 == 7) { keyboard.write('7'); lp2 = lp1; };
  if (lp1 != lp2 , lp1 == 8) { keyboard.write('8'); lp2 = lp1; };
  if (lp1 != lp2 , lp1 == 9) { keyboard.write('9'); lp2 = lp1; };
  if (lp1 != lp2 , lp1 == 10) { keyboard.write('0'); lp2 = lp1; };
however when run end constant stream of numbers based on slider is. if can point out went wrong or show me better way of doing obliged.

code: [select]

  if (lp1 != lp2 , lp1 == 1) { keyboard.write('1'); lp2 = lp1; };
the comma operator not 1 want use. 1 want not @ clear.
