Guest book entries

I'm using FP 2002 on Win XP. I set up my guestbook using
the "guest book form" on FP. The responces appear below
the form. The comments portion of the guest book has no
right margin, the comments extend out to the right
forever. How can I create a right margin. Someone
suggested inserting a table but I don't no where or how to
do that. Any other suggestions would be greatly
appreciated.
Thanks,
Paul
