[Zope] getslice Error?

[Marko MARKOVIC]

Hi all,

with this little code :

<dtml-in "showNSDetails(nsref=old_nsref)" start=query_start>
<dtml-call "REQUEST.set('sdate','%s.%s.%s' %
(ns_entrydate[8:],ns_entrydate[5:7],ns_entrydate[:4]))">
<input type="text" name="new_nsentrydate" value="<dtml-var sdate>"
size="10">
</dtml-in>

ns_entrydate is a field of my query.

i get an getslice error:
