multiple dropdown lists

Hello I have a site where I generate info from the db as follows: a dropdown list with 2 option: once it is submitted the selected data is carried across and this loads selections from the db relevant to the first 2 choices ( doen with javascript to generate 3 dropdowns altogether). Once the 3 relevant choices are amde it is meant to pass acrosse infor to another page which shows all the other data in the db relevant to the last 3 choices. My problem is that only the 3 choices are printed on the last page and none of the other data is shown... can anyone help ? should I post the code ? thank in advance Gianni
