[CCK][Taxonomy] Form

Hello everybody,

By advance, I'm sorry for my English :P (my Frensh is better ... I think)

I inherit a web site under drupal. I only use this tool since 4 days.

I created a content type and I would like to enrich my creation form. Which just content by default a title and a description.
I also created a taxonomy (category).

To build my form, I found a module which seems to be famous : CCK suite (cck, content_taxonomy, addnode, subform_element).

In my content type, I inserted a Taxonomy Field -> Autocomplete, in which I selected my vocabulary (category).
Then, I gave to my user role some right on my vocabulary.

Cool, it seems to work. In my form, I can select the term I already entered manually. I can also add some new terms by this way.

Great but not ^^' :
- I can't find the link between the object I created and the vocabulary term I entered. I hoped find it in the table `term_node`. It seems to have a link but I don't know where !?
- It creates the term even if it already exists in the database. It does that systematically in 2 copies (Oô <- big eyes)
- When I search a term supposed to be linked to at last one object, It find nothing.

I saw a lot of options (I test a lot of combinaition ... quite randomly), but I'm still blocking :
- The rights on the terms
- 'Save options' in the field (Save as tag|Save in cck table|Both)
- The options of field in general

I hope my post will not be a doublon and you will be able to help me.

Thanks by advance

Asmo
