Modal Panel issue

[sugi_chn]

I just tried the following snippet , when i hit submit , i'm getting script error.
Can anyone help me out to access value from modal panel?

<%@ page language="java" contentType="text/html;charset=UTF-8"%>
<%@ taglib prefix="f" uri="http://java.sun.com/jsf/core"%>
<%@ taglib prefix="h" uri="http://java.sun.com/jsf/html"%>
<%@ taglib uri="http://richfaces.org/a4j" prefix="a4j"%>
<%@ taglib uri="http://richfaces.org/rich" prefix="rich"%>





<f:view>
<a4j:commandButton value="Invite New User"
onclick="javascript:Richfaces.showModalPanel('showInviteUser',{width:250,height:300,top:200,left:200})" immediate="true">
</a4j:commandButton>

<rich:modalPanel id="showInviteUser">

<h:inputText id="inviteUserFirstName" maxlength="250" size="10" value="#{userInfo.userBean.userInviteFirstName}"/>
<h:inputText id="inviteUserLastName" maxlength="250" size="10"/>
<a4j:commandButton id="inviteBtn" action="#{userInfo.inviteUser}" value="invite" immediate="true">
</a4j:commandButton>

</rich:modalPanel>

<!-- you don't need a server side component just for javascript window -->
<input type ="button" onclick="javascript:Richfaces.showModalPanel('showInviteUser',{width:250,height:300,top:200,left:200})" immediate="true">



<rich:modalPanel id="showInviteUser">
<h:inputText id="inviteUserFirstName" maxlength="250" size="10" value="#{userInfo.userBean.userInviteFirstName}"/>
<h:inputText id="inviteUserLastName" maxlength="250" size="10"/>
<a4j:commandButton id="inviteBtn" action="#{userInfo.inviteUser}" value="invite" immediate="true">
</a4j:commandButton>

</rich:modalPanel>
