Looking at your form:
<FORM action=http://www.thepoultrylink.com/cgi-bin/aspmailer.asp method=post>
Name of Site: <INPUT size=30 name=name><BR><BR>
URL of Site:<INPUT size=30 name=URL><BR><BR>
Reply to (address): <INPUT size=30 name=from><BR><BR><BR>
<INPUT type=submit value=Submit>
</FORM>
I would personally change the <INPUT size=30 name=from>
to<INPUT size=30 name=reply>
and then change the aspmailer.asp form to suit.
The error:Error!
The following error(s) happened:
No Reply-to address (From) for this letter

Looks like it is trying to find the from field but it is not there as it is already being used.
