instead of <dtml-if next-sequence> try:

<dtml-if "_['sequence-index'] + _['sequence-step-size'] <
_['count-id']">

         <a href="mksuche?query_start=<dtml-var
            " _['sequence-index'] + _['sequence-step-size'] + 1"-->>
         (Zu den nächsten Such-Ergebnissen)
         </a>

      </dtml-if--> 

This seems to work.
