I'm having problems with setting session data from inside an iframe. I have the
main page then you click on the log in button to change the iframe over to a
login box. Once you login I should beable to refresh the main page and the log
in button should change to a log out button.
If you would like to help me directly that would be great. Contact me via IM
anytime.
