So I would still have to ask you this question: How do you register and
array in a session?


$tempslot = array ( "Style" => "$Style" , "Brand" => "$BrandName" , "Colour"
=> "$Colour" , "Size" => "$Size" ,
"Quantity" => "$Quantity" );

session_register('$tempslot');

is that wrong somehow?

Thanks again in advance.
