How can I tell Smart Map to look at Commerce for entries? I have Smart Map working perfectly within Commerce. Meaning, I am able to show a map, etc. when I'm looking at products.

However, I am trying to build a "product locator" to find products in my area.

I am able to successfully pass the arguments to my results page - I can print out the zip code and distance that was chosen, but I am always getting into my "no results found" case.

{% set target = craft.request.getParam('near') %}
{% set radius = (craft.request.getParam('radius')) craft.request.getParam('radius') : 200 %}
    {% set params = {
    'target': target,
    'range': radius
} %}

{% set entries = craft.entries.address(params).order('distance').find() %}


radius is a drop-down of (miles) to choose from. 
near is the name of the text input the user enters the zip.
You need to tell Craft to look within the Commerce section like this:

{% set entries = craft.commerce.products.address(params).order('distance').find() %}
