Display a msg. for members w/ specific subscription

This should be possible, but I don't know how!

What I want to do is display a message on a page only if a member has a specific subscription. I imagine there would be an 'if' statement that I can use for this.

Any help?

Thanks!

Is this in the members page or an outside php page?
In the member.html page:

{foreach from=$products item=p}
{if $p.product_id eq "1"}
what you want to say.
{/if}
{/foreach}

Actually I want to put it in an outside php page.
