Hi Gulis, if you run the page without submitting the form (the first time for example), your variables are not defined. So you can test with this construct: <dtml-if yourcheckbox> ...doing this and that... </dtml-if> HTH Tino Wildenhain Gergely Gulis wrote:

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
