Choose options redirects to home page

The first product on this page just takes the user back to the home page.Other products update the cart or go to a detail page. I just can't figure out why this one product is misbehaving.

Hi,

That's probably because the canonical URL you have in that product is wrong.
Empty the canonical URL field of that product, flush your website cache and try again.

How embarrassingly simple! Thanks Nicolas - perfect!
