Proxy Error, Urgen Help

I build my friend a website and everything was working fine.
Today they told me about an error they were getting when summiting a feed back form. Can any one help me on this urgent help. This is the the web site ( URL ) and then click on Contact . This is the error I get, actually now I'm getting a different error:

FrontPage Error.
User: please report details to this site's webmaster.


Webmaster: please see the server's system log for more details.


Can anyone please help me on this problem. Thank You.

I just viewed the page in Win XP with IE 6 and it worked fine. I will test it on my Mac here in a few with Safari, MSIE 5.2.2, Netscape 7 (runnin in Classic, Mozilla, and any other mac based browsers I have and see if an error pops up.

I still need help. It sometimes gives me an error and sometimes it does not. I try to figure it out but i'm still new at this. When it gives me the error it says to check the system log. Another thing that happend when it does go though is that I don't received the email that I'm suppose to receive. I'm using Frontpage 2002 and Tripod as the host. Thank again for the help.

I don't have a problem either, and i don't see how there could be an error at all. It's a mailto link so it shouldn't open a page at all. The code for the link is

<a ONMOUSEOVER="changeImages('frontmigs_04', 'images/frontmigs_04-Contact_over.gif', 'Contact', 'images/Contact-over.gif', 'frontmigs_12', 'images/frontmigs_12-Contact_over.gif'); return true;" ONMOUSEOUT="changeImages('frontmigs_04', 'images/frontmigs_04.gif', 'Contact', 'images/Contact.gif', 'frontmigs_12', 'images/frontmigs_12.gif'); return true;" href="mailto:dj@migueljusmiguel.com">

Only thing I can think of is if the browser doesn't support javascript, the OnMouseOver and OnMouseOut won't work, so maybe placing the link before them might correct the problem. Try replacing the above code with:

<a href="mailto:dj@migueljusmiguel.com" ONMOUSEOVER="changeImages('frontmigs_04', 'images/frontmigs_04-Contact_over.gif', 'Contact', 'images/Contact-over.gif', 'frontmigs_12', 'images/frontmigs_12-Contact_over.gif'); return true;" ONMOUSEOUT="changeImages('frontmigs_04', 'images/frontmigs_04.gif', 'Contact', 'images/Contact.gif', 'frontmigs_12', 'images/frontmigs_12.gif'); return true;">

Is the e-mail address correct? Mailto link uses local e-mail client so it's not a server-side or code problem.
