Printing a multidimesional session variable

[Anon]

Hi,
I am trying to assign data into a multidimensional array and then register the array as a session variable. Here is what i do:

$foo[$bar]['price'] = $price;
session_register($foot[$bar]['price']);

then i try to print it like this:

<?echo "{$foo[$bar][price]}"; ?>

this is the way the php manual says to do it in php4. is my problem the registering or the printing?

Thanks so much in advance,

JP
