There is a book/CD by 'Stroup' called 'More effective c++'. VERY excellent book. It give someting like 54 specific technicques to employ that save LOTS of time for a C++programmer.
One of the ones from that book, applies here:
DON'T write if ( variable ==/= constant){;}
INSTEAD write if( constant==/= variable){;}
Why, I was waiting for you to ask that question.
If you accidentally write the assignment operator '=' instead of '==/=', the first
case does an assignment, and if the constant is not 0 or unset, the statment will
always be true. In the second case, the interpreter/compiler will error out with the
fact that you can't assign to a constant.
So do this:
$var_to_test = FALSE;
if( TRUE = $var_to_test){;}
if($var_to_test = TRUE ){;}
if( TRUE == $var_to_test){;}
if($var_to_test == TRUE ){;}
and see what happens.

Hi,
You have two problems in these line:
Harlequin said:
if ($_SESSION["Authorised"]="Yes");
1. The obvious ";" at the end of the line.
2. $_SESSION["Authorised"]="Yes" it's different to write:
$_SESSION["Authorised"]=="Yes"
Cheers,
