This assumes you have a script named "topics.php" and that script uses
GET parameter "topic_id" to determine which Topic to display in your
Forum.
It was only a WILD GUESS as to how your forum topics would be
displayed, really... Well, not totally a wild guess, since that's
pretty much how they all work, though they will use different names
for stuff:
forum.php?id=$topic_id
view.php?thread_id=$topic_id
show.php?subject_id=$topic_id
..
..
..
Perhaps you need to set this aside for a while, and work on showing a
list of topics, and the display page for something chosen from that
list.
After you've written that, the link to put in there gets a LOT easier
to figure out.
