Change the above to:

<?php
for($x=0;$x<$_POST['vars'];$x++)
{
  ?>
<tr>
<td width="35%">Number <?php echo $x; ?>:</td>
<td><input name="num[]" type="text" id="vars" value="0" size="25"></td>
<?php } ?>

>     <tr>
>       <td colspan="2"><div align="center">
>           <input name="add" type="submit" id="add" value="Next &gt;">
>         </div></td>
>     </tr>
> </form>

And to do the addition...

$sum = array_sum($_POST['num']);
