This should work: <dtml-in substract> <dtml-if "_['sequence-item']!=''"> update artikel_table set artikel_qty=artikel_qty - <dtml-sqlvar "_['sequence-item']" type=int> where artikel_id=<dtml-sqlvar "artikel_id[ _['sequence-index'] ]" type=string> <dtml-var sql_delimiter> </dtml-if> </dtml-in> __________________________________________________________________ Jim Sanford .

For every artikel (item) I have a description and a number of available items. The page has multiple rows (depending on the database content) in every row is a input-box in wich the user can enter a number. This number needs to be substracted from the available items number of the correct artikel. My question is how can I get the correct tuple of items out of the list. For example In every row I have the substract box and a hidden field with the primary key: <input type="text" size=5 value="" name=substract> <input type="hidden" value="<dtml-var artikel_id>" name="artikel_id"> When I submit the Form I get with the following lines <dtml-in "REQUEST.form.items()" sort> <dtml-var sequence-key>:<dtml-var sequence-item><br> </dtm-in> the content substract = ['12', '', '', '', '', '', '', '', '', ''] artikel_id = ['20000808095658', '20000808095503', '20000808095341', '20000808095744', '20000731135126', '20000808092056', '20000808092333', '20000808092723', '20000808095232', '200007311227'] and this is correct. This means that a user has entered 12 for the artikel_id 20000808095658. How can I get the single values, so that I can use them? How can I extract the values from the list to use the tuple in a sql-statement? Help would be great.
