Variable To Show Product ID on CC Page

I'd like to be able to show content on the "cc_info.html" page depending on the product being purchased.

For example: (this doesn't work)

Code:

{if $p.product_id eq 1}
You Are Purchasing Product #1
{/if}

Problem is, none of the product_id variables seem to work on the cc_info.html page.

What is the variable I can use to identify the "product_id" inside the cc_info.html page?

nevermind..

Funny I've been trying to figure this out for months... and I just got it after posting above.

This Works:

Code:

{if $payment.product_id eq 1}
You are purchasing Product #1
{/if}
