[Zope] How to Use Javascript returns in DTML tags

[Scheck, Herman]

I am trying to simply use the return (rfqNumber) from a Javascript script as
a variable in a DTML tag (see code below).  I've also tried placing the
Javascript code in-line to the DTML, as well as trying to encapsulating the
script in a DTML method.  None of this seems to work.  Yes, I am fairly new
to DTML (and Zope, for that matter).  I have seen articles on how to pass
arguments from DTML to Javascript functions, but not on how to use
Javascript returns in DTML.  Can anyone point, push, or drag me in the right
direction?
 
Thanks in advance for any help.
 
<SCRIPT LANGUAGE=JAVASCRIPT>
   <!--
      function GetRFQNumber{
 
rfqNumber=parent.frames('fraQuoteRequest').document.all['QUOTEREQUEST'].inne
rText;
         return rfqNumber;
      }
   -->
</SCRIPT>
