Calling the Product ID number from Members area

Hi,

Can anyone tell me if its possible to call the product ID number from an amember powered members area...??

Im using the incremental content plugin, and want the user to be able to link directly from my members area to:

Code:

http://mysite.com/amember/plugins/protect/incremental_content/?product_id=*

But obviously the * in the link above needs to be created differently for each product id. So im assuming will need to look something like:

PHP:

http://mysite.com/amember/plugins/protect/incremental_content/?product_id=<?php echo $_SESSION['product_id']; ?>

But I can't seem to find what $_SESSION['product_id'] needs to be to achieve this. Can anyone help on this?

Thanks guys
