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 >"> > </div></td> > </tr> > </form> > > This is only a snippet, there is more to it but for simplicities sake... > Then I calculate it.

And to do the addition... $sum = array_sum($_POST['num']); ---John Holmes... -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
