Hello all, I'm trying to parse input from a form to convert all string input to upper-case, before passing it on to a SQL method. So I created a DTML method to do this. In this 2nd DTML method, I call a ZSQL method to obtain the table's column names, then use the column names to access the corresponding values in the REQUEST. I must not be implementing indirect variable lookup correctly, because the script below produces the following error. How do I debug this? Thanks. Zope Error Zope has encountered an error while publishing this resource. Error Type: TypeError Error Value: read-only character buffer, instance My DTML method looks like this: <dtml-var standard_html_header> <dtml-comment> Loop over fieldnames in the family table, to lookup corresponding values in the REQUEST, then convert all lower-case values to upper-case. </dtml-comment> Before: firstmiddle=<dtml-var firstmiddle> <dtml-with get_one_family> <dtml-in names> <dtml-call "REQUEST.set(_['sequence-item'],_.string.upper(REQUEST[_['sequence-item']]))"> </dtml-in> </dtml-with> After: firstmiddle=<dtml-var firstmiddle> <dtml-comment><dtml-call update_family></dtml-comment> <dtml-var standard_html_footer> #####end#### -- irene barg ---------------------------------------------------------------- Irene Barg Email: ibarg@as.arizona.edu Steward Observatory Phone: 520-621-2602 933 N.
