hi there samer thanks for the fast reply,


eh does this mean i need to create a new php page and i will have to add this action,form in the new pages and for each new created link. Im having more then one link on each page. To be more precised its a xml data feed that i like to edit and let it redirect to a new landing page. I never done something like this before.The data feed is updating itself constantly.
