Session variable error

I am doing the following but gets below error

     <cfif err_Login EQ " ">
           <cfset session.Username = #form.txt_UserName#>
          <cflocation url="usersMenuForm.cfm">  
     </cfif>

In usersMenuForm.cfm the following message is displayed when doing <cfoutput>#session.Username#</cfoutput>

Element USERNAME is undefined in SESSION

do you have session management turned on in your application.cfm?

<cfapplication name="yourApp" sessionManagement="yes">

<cfapplication name="usersValidateForm" sessionManagement="yes">

      <cfif err_Login EQ " ">
             <cfset Session.Username = #form.txt_UserName#>
            <cflocation url="usersMenuForm.cfm">  
      </cfif>

<cfoutput> #Session.Username#</cfoutput>

This is a duplicate of the other question here:

As I answered there:

 well, are you sure it is being set?

Really the code should look like this:

<cfif Len(Trim(err_Login)) EQ 0>
       <cflock scope="session" timeout="10" type="exclusive">
           <cfset session.Username = form.txt_UserName>
       </cflock>
        <cflocation url="usersMenuForm.cfm">  
</cfif>

Also if you don't have session management turned on in your application.cfm file or if you have cookies disallowed then this will not work.

If cookies are disallowed you can try

<cflocation url="usersMenuForm.cfm">   --> <cflocation url="usersMenuForm.cfm" addtoken="yes">

Try this,
<cfdump var="#session#">

Just type that in at the bottom of a page to see all of your session variables.

Also to keep yourself from going nuts, try to put a else statement when trouble shooting.  There might be a problem with the IF statement that is not setting your user name.  So else <cfset session.Username = junglebook>  If you see your else statement then you know it is something wrong with your if statement not the application, or it's sessions.
