Listbox

[Geno]

Hello,

I have 2 listbox.
The first one is the list of users that cant have acces to a page and the second one is user that can have acces to the page. What I want to do is

Cant Can
--------- ---------
|User#1| >>> |User#3|
|User#2| <<< |User#4|
--------- ---------

So when you click on <<< or >>> it adds the user youve selected in the different mysql table. With some javascript code, users would move between the 2 boxes.

I would like to know how you can do that ?

Thanks !
