[Zope] REQUEST variable is not being modified by Zope Python script

[David Hassalevris]

Try changing
>   <dtml-call expr="incrementRowLength(counter)" -->
>            <dtml-var counter>
to
<dtml-call expr="counter= incrementRowLength(counter)">
<dtml-var counter>

Or inside the python script, push the new value of "counter" back into the
REQUEST object:
