Hi, I am new at Zope. So I have difficulties while i am building a website. The problem: I use the Zope's own SQL database. I'd like to insert datas via Web into it. I wanna give some information with checkboxes, but as far as i know, if i do not select a checkbox, the HHTP request do not contain the value of the variable belongs to that checkbox. When I am defining the SQL insert command (as a query), I have to give the input arguments. So if i do not check a checkbox, the ZSQL Method screams for it. 1. At first i tried to define the table with default values, Error message No 1. 2. Then I tried to define the variables belonging the checkboxes in the folder as a propertiy with unchecked value, Error Message No. 2. I have no more idea. How can I solve this problem? Thanks in advance, Gergo
