Dave,
I've searched CMS 1.15 and I can't find that snippet of code anywhere. I do find "echo $value" in the list.php file, but it's in a line of code that is different than what you suggested above, see below.
<td class="<?php echo $bgColorClass ?>"><?php echo $value ?></td>
I've attached the version of List.php I have installed.... I upgraded from 1.05 to 1.15 if that makes any difference. I can't find the snippet $tdAttributes anywhere either.
