How to make a simple checkbox in CCK
To make a simple, single checkbox with a CCK field, Agaric thinks the best approach is:
Give it a label (this is not what will appear next to your checkbox; it is what will be used as a title above it)
Single on/off checkbox
The key is the allowed values list– you need two:
0|Check this box to fill out a profile for another organization you represent.
1|Check this box to fill out a profile for another organization you represent.
There you are!
Agaric uses this with workflow-ng to redirect you to an organization form if the box is checked.
