Hi people,

I developed a site with a graphic rollover image navigation in javascript, one of my clients says he keeps getting error messages, specifically "Line 70: n_guestbook_on is not defined".
I think he uses Netscape (don't have the version number) on a Macintosh machine.
Could you have a look at the site http://e-vision2050.ethz.ch and tell me if you get an error?
I used the popular code for rollovers, which is also featured in one of devsheds columns

Many thanks,
Alex Suzuki
