I am trying to do the next thing in Drupal 6.2 (yes... i know it is old..):
I have a content type(FOOD) that contains a node reference to a a taxonomy(SWEETS), that taxonomy have 10 values(CAKE, CANDY, LOLLYPOP ...).
I have some users, I added profile check boxes. Those check boxes are selected by each user. the check boxes have the same value as the values in the SWEETS taxonomy I described earlier.
