Problem in WML code

I am trying to send the values of 'user_name' and 'user_password' from "LoginForm.cfm" to "FormValidation.cfm" using 'post' method, but the code displays errors. Can someone please help me whats wrong with this code.

<!---LoginForm.cfm --->

<CFCONTENT TYPE="text/vnd.wap.wml">
<?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="LoginForm" title="Login Form">
<do type="accept">
<go href="FormValidation.cfm" method="post"/>
<postfield name="user_name" value="$(user_name)"/>
<postfield name="user_password" value="$(user_password)"/>

</do>
<p>
Name: <input type="text" name="user_name"/></br>
Name: <input type="text" name="user_password"/></br>

</p>
</card>
</wml>
