  data entered or not. As it is scanner  no browser tabbing by user .</p>
  
  <pre><code>&lt;tr&gt;
  &lt;td class='form'  align='center'&gt; &lt;input type='text' tabindex=1 onkeyup='moveNext(this);' id='from' name='elem1' size='5'  value=''&gt;    &lt;/td&gt;
      &lt;td class='form'  align='center'&gt;&lt;input type='text' tabindex=2   onkeyup='moveNext(this);' id='item' name='elem2' size='5'  value=''&gt;   &lt;/td&gt;
      &lt;td class='form' align='center' &gt;   &lt;input  type='text' tabindex=3   id='calc_price' size='10'  name='elem3' value=''&gt;  &lt;/td&gt;
