I am at my wits end, absolutely stuck.

I am runnning a picklist script and it generates the following query string:

addPage.php?pageTitle=&PickList%5B%5D=11&PickList% 5B%5D=12&PickList%5B%5D=15&pageId=2005-120-14-8-0

How on earth do I handle the variables using php or javascript in the query string as they all have the same name?

Can anyone help

PLEASE !
