ok, thanks - I'm getting there - but it's excruciating! Thanks to you, I'm beginning to understand. I think I have it working. There seems to be a problem with logging out - I have a page called 'admin_LogOut.php' and it seems to do nothing- doesn't end the session. Leave it with me - I think I need a break.
The next question is let's say I change the customers table to members table - so now I have an 'admin table' and a 'members table' - how do you allow those members in the members table to login and edit say their details in 'members_Detail.php' ? Does that make sense?
