Okay I got closer. By adding the if statement using $thread[threadid] in the threadbits template I got alternating rows. However, the colors are assigned by thread ID so they dont' alternate properly. If someone posts to a thread, it moves up in the list, but retains it's originally assigned class.
So.. with this...
Code:
<if condition="$thread[threadid] % 2 == 0">class="alt2"<else />class="alt1"</if>
can anyone help me make that statement conditional on the display order of the thread rather than the thread ID? I did try $thread['displayorder'] but that didnt' work at all.
Thanks.
