[FX.php List] php 5 problems: I have tried to copy my existing scripts to php5 enabled servers

[Dale Bengston]

I have no problems with multi-level arrays in $_SESSION. I think your  
problem is related to whether those $_SESSION values, nested or  
otherwise, are actually set when you try to evaluate them in your if  
statement. What happens when you print_r($_SESSION) above that if  
statement?

PS I also have big trouble with PHP 5 if I use <? to start a block of  
PHP code instead of <?php.
