Using WML to pass a variable to a second page

I have created a page for user input.  There is only one input value, and this displays just fine.

Page1

<?xml version="1.0"?><!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>
<card id="card1" title="form1">
<p>
Company Name: <input title="user" name="company" />
<anchor>
Login
<go href="http://65.65.65.131/wireless/search.wml" method="post">
<postfield name="company" value="$(company)"/>
</go>
</anchor>
</p>
</card>
</wml>

The receiving page, gives me a 'This page can not be displayed' error.  If I then refresh the response page (search.wml), it does load the page, however the value passed is not displayed.

Page 2

<?xml version="1.0"?><!DOCTYPE wml PUBLIC "-//WAPFORUM//DTD WML 1.1//EN" "http://www.wapforum.org/DTD/wml_1.1.xml">
<wml>
<card id="card1" title="form1">
<p>
<?php
echo 'Company: ';
echo $_POST['company'];
?>
</p>
</card>
</wml>

Is there something else that needs to be done to pass a value to a separate page.  I will eventually be using this value ot query a database using PHP and therefore cannot just use separate cards in the same wml document.

Thanks so much,
Stephen
