Problem with formmail on the index page but not the other pages

For some reason the formmail that I have on the index.htm page has a problem. I get the following error: The requested URL /cgi-sys/formmail.pl was not found on this server.

I'm using the same formmail script as I'm using on another page on the same directory, which works, here is the script:

<FORM ACTION="/cgi-sys/formmail.pl" METHOD="POST" name="allhometv" id="email">
<p><strong>First and Last Name:</strong><br>
<input name="name" type="text" id="name" size="35">
</p>
<p><strong>E-mail Address:<br>
<input name="email" type="text" id="email" size="35">
</strong> </p>
<p>
<input name="submit_btn" type="submit" id="submit_btn" onClick="MM_validateForm('name','','R','email','','RisEmail');return document.MM_returnValue" value="Get Free Video Now!">
<br>

<input name="recipient" type="hidden" id="recipient" value="myEmail@company.com" />
<input type="hidden" name="subject" value="user email info" />
<input name="required" type="hidden" value="name,email" />
<input type="hidden" name="env_report" value="REMOTE_HOST,REMOTE_ADDR,HTTP_USER_AGENT" />
<input type="hidden" name="sort" value="name,email" />
<input type="hidden" name="redirect" value="http://www.company.com/signup/sign_up.html" />
<br>
</p>
</form>

Does anybody have any idea what is going on?

Thanks
