I'm trying to get my forums to look similar to the Project Opus forums using flatforum. I've copied the style.css from http://drupal.org/node/73542#comment-117209 and hacked it about a bit. I'm struggling with the little banner at the top of each comment with its post date, you can see what I've managed so far at http://samsoc.co.uk/forums/site-discussion .

Hi,

I've been trying to output a value from multiple merged cck fields in a table cell, and I could use some help.

I have three multiple-value fields ($field_one, $field_two, $field_three) stored using a cck made content type.
