Hi, this is my first posting to the list, and about my 4th day working with Zope. I have a bit of a problem. All my code so far is working well. Just the following section is defying my attempts to make it run. What it does is to update a field in the database (to allow employees to quickly update their hours in the hours tracking thing I'm creating) it's complex since all the employees hours will be listed on one page and will be instantly updatable (with a select box that allows the choice of +/- (name is modify<dtml-var hoursID> and value is either + <hours already input> or - <hours already input>) and a text field for entering hours to add or subtract (name is mod_hours<dtml-var hoursID>)). The code (in the DTML document) is: <dtml-in "REQUEST.form.items()"> <dtml-if "_.string.find(_['sequence-key'], 'mod_hours')"> <dtml-else> <dtml-let mykey=sequence-key myval=sequence-item> <dtml-in "REQUEST.form.items()"> <dtml-if "_.string.find(_['sequence-key'], 'modify')"> <dtml-else> <dtml-if "_['sequence-key'][6:9] == mykey[9:12]"> <dtml-if myval> <dtml-call UpdateHours(REQUEST)> </dtml-if> </dtml-if> </dtml-if> </dtml-in> </dtml-let> </dtml-if> </dtml-in> and the SQL method UpdateHours is: update emp_hours set hours = <dtml-var expr="_['sequence-item']"> <dtml-var expr="_['myval']"> where hoursID = <dtml-var expr="_['mykey'][9:12]">; with arguments: sequence-item, myval, mykey I've tried everything I can think of but it not only refuses to do anything, it also refuses to raise an error. If anyone can help out I'd be very grateful. Thanks Mike Kelland mike@studiomatic.com
