PHP Scripting question?

[DIVAD3]

Also Mark I think the missing element might have to do with what it says here in this part of the script at the bottom:

// Then you need to make sure the database you want
// is selected.
mysql_select_db($db);
?>

Perhaps there is something I should be putting in this line???? OR NOT! it really doesnt make sense to me that I should be touching that part of it.
---------------------------------------
Just exactly what the variable is-is something I am not understanding. what is the variable as you were implying???
