well i want to change a form so it changes its form when you click it

for example : if i were to have a login button and when clicked it logs the person in and the page changes in a frame, then after it has been clicked the form button text changes to "logout" and the form action changes for the person to logout.

can this happen, if so add me on msn : sandeep.singh.bansal@hotmail.com

or email me : sandeep.singh.bansal@gmail.com

i need this urgently

You are going to require a server-side script / application (ie - php, asp) to do that.
