CGIemail script working in Safari but not Firefox or Opera

Question

Here is the text file I am linking to:

To: [email protected] Subject: DDD Message

From: [name] Email: [emailaddress] Message: [comments]

[$HTTP_USER_AGENT]

and here is the html I am using:

<form id="myform" action="http://darrondavisdesign.com/cgi-bin/cgiemail/cgiemail/myform.txt" method="post" enctype="text/plain" name="info" target="_top">

    <INPUT TYPE="hidden" NAME="success" VALUE="http://www.darrondavisdesign.com/messagesent.html"&gt;

    <h1>Leave a message.</h1>

    <div id="inputs">


    <label for="name">
    <h5>Name</h5>
    </label>
    <input name="name" type="text" size="20" id="name" title="First and last name." />

    <br />

    <label for="emailaddress"><h5>Email Address</h5></label>
    <input name="emailaddress" type="text" size="20" id="emailaddress" title="/>

    <br />



    <label for="comments"><h5>Message</h5></label>
    <textarea name="comments" rows="8" cols="50" wrap="soft"></textarea>

    <br />

    <input type="submit" value="Send" class="submit"/>

    </form>

Like I said, works perfect in Safari, but not Firefox or Opera. Also, do you know how to add the text from the default "success" page to an alternate page (in my case, darrondavisdesign.com/messagesent.html)?
