Homework - ajax or java script and php

Hi all, I need help with this problem: we have a table in mysql with following fields: 1. First Name 2. Last Name 3. Age 4. Location 5. Sex 6. Job in a php page I will have a table like first name | last name | age | location | sex | job | -------------------------------------------------------------------------------- --please select-- | A | B | C | D | E | --------------------------------------------------------------------------------- *SUBMIT* | *ADD NEW ROW* Description first when i open the page i have like i described up. On the dropdown from first name I need to select a name from the list from the mysql, I have all first's names here. After I select one of them i need that input text A to be filled with last name , input text B filled with age and so on till E filled with job - of course those values are from the db and corespond to first name selected. Then I can submit that form to insert it in another table or I can choose to add another line on this and do the same... I am here for any other questions or clarify . Thank you
