Please assist /w Guestbook 1.5

I had my guestbook working fine, I have no idea what happened, but the script itself is working fine cause I am still able to log into my admin and do things. But I am appearently missing SOMETHING cause NOW when I try to add an entry into my book, I get this error message:

Guestbook - Error
Cannot add entry to guestbook because the html tag
<option value="guestbook.html" selected>Guestbook</option>
was not found in some guestbook files.

Could anyone please assist me in tryin to figure out what it is that was done to mess my book up. I really like this script, and would hate to get rid of it cause I can't figure it out!

Feel free to email or message me with any help if you rather not post here. My site is at: http://www.WWASims.com. Any help would be GREAT!!

Thanks in advance!

NEVERMIND!!

I was able to figure it out.
