Thank-you, Stefan,

it looks obvious when you get it to work; the pass through works the same way the XSL does.

got myself confused somewhere in the process.

so now I have 3 test pages that give the same output result:

1.  parameter hardcoded to end of XML URL.
 DNN page URL
   http://dnn.wbtdev.net/Home/XMLTest/tabid/58/Default.aspx
XML URL
   http://feed.mysite.org/lgic/profile-open?code=zaw

xsl: uploaded local file: profile-opentvw.xsl  - is the same for all 3 test pages.

2. Static parameter passed to XML URL
 DNN page URL
   http://dnn.wbtdev.net/Home/XMLTest/XMLtest2/tabid/61/Default.aspx
XML URL
   http://feed.mysite.org/lgic/profile-open
Querystring Parameters
 Name    Required  Data Origin        parameter value to send
   code     x             Static Value       (zaw) 

3.  dynamic parameter passed from page URL to XML URL
 DNN page URL
    http://dnn.wbtdev.net/Home/XMLTest/XMLtest3/tabid/62/Default.aspx?language=zaw
XML URL
    http://feed.mysite.org/lgic/profile-open
Querystring Parameters
 Name    Required  Data Origin                            incoming parameter name
   code    x              Pass-Through QueryString      (language) 

thanks again for all your work on this very useful module. Looks like I can set up more than one incoming Querystring parameter to pass on to the XML URL. I will test that next.

If I can be of any help in writing up some user documentation for this module, let me know. I would like to contribute in some small way to the community.
