Newbie : question
Hi, I have a problem with invoking a DTML method.

Search(Directory)
          |
          |
        Catalog(ZCatalog)
                          |
                  |
                     updateCatalog(DTML Method)

DTML Method source of updateCatalog:
   <dtml-call "manage_catalogClear(REQUEST,RESPONSE,URL1)">
   <dtml-call "manage_catalogFoundItems(REQUEST,RESPONSE,URL2,URL1, ['Image','File'])">

I would like to invoke updateCatalog from the Search directory from a form but when I use
  <dtml-call "catalogue.updateCatalog(None,_,'')">  
to do this, the next error is generate by Zope:
 Error Type: NameError
 Error Value: global name 'manage_catalogClear' is not defined

If I use the next code in the Search directory always in the form,
   <dtml-call "catalogue.manage_catalogClear(REQUEST,RESPONSE,URL1)">
   <dtml-call "catalogue.manage_catalogFoundItems(REQUEST,RESPONSE,URL2,URL1, ['Image','File'])">
Zope say that  the global name 'manage_catalogView' is not defined

If everyone can tell me how to define 'manage_catalogClear' and manage_catalogFoundItems in Search directory
                            or   how to update a Zcatalog from his parent folder
                            or   how to invoke method (which invoke herself methods)from a parent directory,
I would be very pleasant.

Greetings, Akh
