first I tryied  to wrap arround  a SQL statment in ZSQL method:

                          <dtml-try>
                             select bla bla bla.....
                          <dtml-except>
                              <p> Not found</p>
                          </dtml-try>


then I tried to wrap arround the ZQL method
                           <dtml-try>
                                 <dtml-var myZsqlMethod>
                           dtml-except>
                              <P> not found</p>
                          </dtml-try>

       The problem is not the error itself because it is working. What I
want to do is to handle the errors.
