guestbook 2.3.1 problem

i installed the guestbook and customized it, but now it won't let me sign it.. not sure what i did wrong.. when i sign it i get:

Guestbook - Error
You forgot to fill in the Name field. Please correct it and re-submit.

that's a separate page that it goes to, not the pop up.. and, of coarse, the name really is filled in... so i dunno why it is doing that.

check it out at http://winterfell.org/guestbook

try to post and i'll bet you get the error too

i think i fixed it.. i was using some saved template info from the 2.2 version and it wasn't liking that.. once i went in and updated it to use the new stuff it seemed to work fine.. neat!
