Thanks Charles, that code helps a lot. From reading it over I
understand how it works, However, it's giving me one parse error on
the line with a single double quote. Is it possible to combine the 2
lines below or escape the quote somehow... I'm not familiar with
escaping javascript like in php.
--- Code ---
extrafield += ' value="<?php echo $listcreate->' + padded_counter;
extrafield += '->EditValue ?>"></td></tr>';
--- Code ---
Thanks.
