well i have a form on the one page of my site that sends some variables accross using POST to another page. then some other things get calculated however the same variables from the first page need to be sent through to the next page.
and when i click a return button 'Link' to take me back to the previous page the variables are viewed as:
-----
Notice: Undefined index: daysOfMonth in C:\wamp\www\Universal Innovation\date_picked.php on line 2
-----
Please - how can i send variables accross from page to page and back again easily???
any help would be great
