Ok, i need help making two list boxes. One is dynamically filled with results from an sql query ( i think i can do that). The second is then empty. The user will double click a value in the first box and it will be moved to the empty box. Then when submitted, the values in the second list will be sent to the database via sql.

How can this be done? will i need to use javascript?
