frist step

<cfapplication name="" sessionmanagement="yes"> in app.cfm

then in your login.cfm
query to check in authentication....
<cfquery name="qryLogin" datasource="#application.sDataSource#">
        get all the details of user if authentication passes
  </cfquery>

then write the followign statements to keep the values of the logged in user in to session variables
      <cflock scope="session" timeout="10">
       <cfscript>
            session.userid = qryLogin.id;
            session.username = qryLogin.name;
            session.location = qryLogin.location;
            
       </cfscript>      
      </cflock>

in pages you want you can display name  just say #session.username# and and want to diaply location #session.location#
 
 

ok, thanks for your help so far. just need a bit more from you.

this is my application.cfm so far do i need to add anything else?

<cfapplication sessionmanagement="yes"
setclientcookies="yes"
name="user_details"
sessiontimeout="#CreateTimeSpan(0,0, 20, 0)#"
sessionmanagement="yes"
> 

this is my login page so far do i need to add anything else?


<cfif IsDefined("FORM.email")>
  <cfset MM_redirectLoginSuccess="../index.cfm">
  <cfset MM_redirectLoginFailed="failedlogin.cfm">
  <cfquery  name="MM_rsUser" datasource="ukdiscountproducts">
  SELECT email,user_password,user_level FROM registered_users WHERE email=<cfqueryparam value="#FORM.email#" cfsqltype="cf_sql_clob" maxlength="255"> AND user_password=<cfqueryparam value="#FORM.user_password#" cfsqltype="cf_sql_clob" maxlength="255">
  </cfquery>
  <cfif MM_rsUser.RecordCount NEQ 0>
    <cftry>
    <cflock scope="Session" timeout="30" type="Exclusive">
      <cfset Session.MM_Username=FORM.email>
      <cfset Session.MM_UserAuthorization=MM_rsUser.user_level[1]>
    </cflock>
    <cfif IsDefined("URL.accessdenied") AND true>
      <cfset MM_redirectLoginSuccess=URL.accessdenied>
    </cfif>
    <cflocation url="#MM_redirectLoginSuccess#" addtoken="no">
    <cfcatch type="Lock"><!--- code for handling timeout of cflock --->
    </cfcatch>
    </cftry>
  </cfif>
  <cflocation url="#MM_redirectLoginFailed#" addtoken="no">
  <cfelse>
  <cfset MM_LoginAction=CGI.SCRIPT_NAME>
  <cfif CGI.QUERY_STRING NEQ "">
    <cfset MM_LoginAction=MM_LoginAction & "?" & XMLFormat(CGI.QUERY_STRING)>
  </cfif>
</cfif>

<cfquery name="qryLogin" datasource="#application.sDataSource#">
 SELECT *
 FROM registered_users
  </cfquery>



so where about does this bit go??
<cflock scope="session" timeout="10">
       <cfscript>
            session.userid = qryLogin.id;
            session.username = qryLogin.name;
            session.location = qryLogin.location;
           
       </cfscript>      
      </cflock>


thanks
