Hello Davide,

The problem you're having is with how you must define the parameters in your field and widget.

When defining an option widget (single checkox or radio button), the "Label" field is not used. The instructions for the field (at the top) say (in english):

For a 'Single on/off checkbox' widget, define the 'off' value first, then the 'on' value in the Allowed values section. Note that the checkbox will be labeled with the label of the 'on' value.

So:

You must enter two (and only two) parameters in the "Allowed Values list:" text area
the format of the lines must be "value|label", (and the label of the first line is effectively ignored).

For example, say you wanted:

A simple "Yes/No" question for the user
The value returned stored in the database to be "1" or "0",
you want the label to be "Yes" (and the user must select "yes" in order for the value to be stored to be 1),

You should put the following in the Allowed Values section:

0|No
1|Yes

The weirdness about this format has to do with the way the module author wanted you to be able to switch the field type from radio/checkbox to list of radio buttons without having to change anything except for the "Widget" type in the CCK field definition.

For more information about this, see http://drupal.org/node/115026, and the comments by jsenich (comment #15), and yched (comment #16).

Hi all, I have a problem with CCK (1.6-1) on my new Drupal installation 
(5.7).

I can create a Text Single sign on/off field (checkbox or radio button), 
but with some errors:

1) The label is not associated to the field. See the two image attached.

2) When I check the field, my check is not stored in the DB so when I 
re-edit the node I see that the field is not checked.

Any help ?
