Programming LCD display for swtching between inputs

Oh sorry about the comment. It was wrong.

if (setState == HIGH)            // if the state has changed, move the cursor to next input
    { 
      lcd.setCursor(5,0);
      lcd.noBlink(); 
      lcd.setCursor(15,0);
      lcd.blink();
    }

So how should I change the above code to make sure that the cursor indeed switches to the next input..I am stuck here and can't move. Hope you can help me out
