[Zope] Trouble accessing posted variables outside namespace

[Doug Goodwin]

Hey Zope fans,

I'm having trouble with variables. My user has just submitted a 
registration form and I want to do the following things:

1. Check to see if the posted email address exists in my users table
  |
  |--If so, send a email message reminding them of their username & passwd
  |
  |--If not, insert the posted variables into the dB & send welcome email

I'm having trouble accessing variables I can use outside of the 
<dtml-in ...></dtml-in> namespace. IS there a way to create a global 
array, stuff all the form info into it on hitting the page and then 
manipulate items within the array with methods? That would be way 
cool.

Thanks in advance -- the code fragment follows.

Here's a code fragment:

<dtml-call "REQUEST.set('userexists', 'UNKNOWN')">
<!-- username is set to the user's email address -->
<!-- Check our SQL dB to see if this email address already exists -->
<dtml-call checkemail>
<dtml-in checkemail>
  <dtml-if expr="username == '' ">
   <dtml-with REQUEST>
   <!-- How do I get the values of these variables outside checkmail?-->
    <dtml-call "REQUEST.set('username', username)">
    <dtml-call "REQUEST.set('password', password)">
    <dtml-call "REQUEST.set('userexists', 'FALSE')">
   </dtml-with>

   <!-- Send the welcome email -->
  <dtml-else>


   <dtml-with REQUEST>
    <dtml-call "REQUEST.set('userexists', 'TRUE')">
   </dtml-with>

   <!-- Send the reminder email -->

  </dtml-if>
</dtml-in>
<dtml-if expr="userexists == 'TRUE' ">
