Hi James,
Ah, I was definitely having a newbie moment before. Thanks for the pointers.
I had one other issue getting comments working (on a page that actually merited the "dynamic" name):
I was getting errors from format_general_comment, that it wasn't being passed $content. In the end, I took out the and merged lines 88 and 89, and now it works beautifully.
Thanks!
Cathy
