Sorry is this is a second posting

On 16 jul 2002, you wrote in ZopeList:

Hope I'm not wrong, but i think this should cache 'yourquery' for the 
<dtml-in>. 

<dtml-let query_result=yourquery total="_.len(query_result)">
<dtml-in expr="query_result" size=x>

</dtml-in>
</dtml-let>

On the other hand, i'd be interested to know how you get results x and y in 
'x to y of total' 


cheers, Dirk
