WooCommerce, variations, and missing 'Add to Cart'

[KAIROS]

Hello.

I am using WordPress with the Church Theme.
I have set up a Product with two variations.
When I go to the live page, and select one of the variations, the 'Add to Cart' button (+ # of items, etc.) doesn't show up.

I came across a discussion of the same prob on this forum:
https://github.com/woothemes/woocommerce/issues/1514

In it they ask, "Do you have wp_footer(); in your themes footer.php page?".
Genesis *does* have wp_footer(); in the theme, so I'm stumped.

Any ideas??

Thanks.
