[Zope] newbie question on TAL

Hi all, I have created 3 new metadata (Elements) in portal_metadata (named "French_name", "Dutch_name" and "institution"). They are called by a python class (product). In the edit_form, I wish to call the values of the French_name and Dutch_name metadatas in a <select> tag using TAL; so I can select one of the values which will be placed in the institution metadata. I no that this is basic stuff , but I'm new to TAL and python. Thanks in advance for any answers. Fnk.
