this is the standard behaviour in a HTML form. To avoid this problem we include an line like this: <dtml-if "REQUEST.has_key('CheckBox_name')"> <dtml-else> <dtml-call "REQUEST.set('CheckBox_name', 'N')"> </dtml-if> in the method that receives the form data. Hope this help =?iso-8859-1?Q?Beuserie_Fr=E9d=E9ric_=28stbrice_dsi=29?= escribió:

hi,

it seems to me that the variable name corresponding to a checkbox into a form is not pushed to the namespace of the SQL query when it's not checked. if it's checked, it works fine. the error reported is related to the argument list entry corresponding to the name of the checkbox into the zsql method.

thanks a lot.
