Help needed - please check site

Hi I am very new to dynamic web site (I am using GoLive6 on Mac together with php & mySQL) and I am very confused about "variables". I would appreciate your feedback on my first dynamic site http://www.vergelegen.co.za (Media section - login test - password test). 1/ There are quite a few things that don't work yet but the main issue is to use session variable to check if the Login_Name is authorize to browse the site and later on if it has admin access to update/delete records in the database. I also want to pass the value of Login_Name from Search to EditProfile... How do I do that with Session Variables? http://www.vergelegen.co.za/xDBMedia/AccessPassword/Login.php?First=1 -> http://www.vergelegen.co.za/xDBMedia/DBMedia/Search.php?First=1 -> http://www.vergelegen.co.za/xDBMedia/AccessPassword/EditProfile.php?Login_Name=test -> ... 2/ My other concern is how do I secure the database? -- Kind regards, Paul.
