Are you trying to say that you want to have both these fields act as a single block, and when a user clicks on any one, the other should appear too.
something like - we can have 2 cck fields "First name" and "last name", clicking on add more will add another set of these 2 fields.
If so, this can be achieved by Flexifield module (http://drupal.org/project/flexifield) used by CCK.
You need to define a content type and add cck fields, then mention these fields as Flexifields, and Voila, your work will be done :)
Hi guys,
i have 2 cck-fields set to unlimited values to allow people
to add as many as they like.
Is it possible that if someone clicks on "add more" (on cck-field 1) that there will
be a new entry added on the cck-field 2 automatically.
Thanks for the help.
Florian
