Less is more. I'm telling my problem directly.
I have CCK, fieldgroup_table and node relavity, so I can create my fields, use node reference on them, group them and create tables using fields. What I try to perform is creating a big table, lets say 5 columns and 25 rows. I create 5 fields with multiple values via CCK and design the table via fieldgroup_table. Up to there, no problem.
First thing: I can't have more than 3 rows in the table since multiple values only allows for three. Need something that user speficies first the number or some Ajax stuff like "add another".
I have found a patch for CCK on http://drupal.org/node/81197 but I don't think that works for Drupal 5. Does anyone know what changes should be made to get it work on 5.0.
If we can solve it, the second problem comes. Lets say I would like to use second column of every row as a node reference field, which is possible. But the node that I would like to reference is not created yet. As I enter a value to that field, I want a node (with another content-type - but same content type for all 2nd column values) be created and titled with that value, linking to the brand new node. So that, after finishing my work with this node. I can click through the links at the 2nd columns, reach each node, then edit it.
So this must be something needs node_save function. But I couldn't handle it at all.
