Thank you that was an error. We are getting closer but I am still getting the error:

d3forum_comment does not set properly.

Even after correcting the mistake:
<{d3forum_comment dirname="(discuss)" forum_id="(3)" class="BulletinD3commentStory" mytrustdirname="bulletin" id=$story.id subject=$story.title}>

My problem must be in the forum path. I have tried all combinations of paths to directory. But still get the error message.
