How to read another Text element value while customising element?

Question

What I Did:

Step 1: I have made two text element (let say name of elements are userName and UserId) in "Test" authoring Template. Step 2: I have customized the first element( userName) by using jsp.

But while customising first element(userName) I need to fetch the second text element( UserId) value into userName.

I am able to get the value of first Text element(UserName) by using below Code but How I will get the second element value?

<%@ taglib uri="/WEB-INF/tld/portlet.tld" prefix="portletAPI" %>
<%@ page import="com.ibm.workplace.wcm.api.authoring.CustomItemBean" %>

<portletAPI:init />


<% 
CustomItemBean customItem = 
(CustomItemBean) request.getAttribute("CustomItemBean"); 
customItem.setSubmitFunctionName("myoptionsubmit");
String fvalue = (String)customItem.getFieldValue();

%>

<script language='Javascript'>
function myoptionsubmit()
{
document.getElementById('<%=customItem.getFieldName()%>').value = 
document.getElementById('<%=customItem.getFieldName()%>_mycustomoption').value;
}
</script>

<INPUT id='<%=customItem.getFieldName()%>_mycustomoption' value="<%=fvalue%>">
