Mobile Redirect

I work for a non-profit, and we use Drupal for our site. The site has 5 homepages, each of which uses a separate URL. We're trying to get make it so that just one of the URL's is mobile-optimized, so we set it up using Duda Mobile software. Everything is working fine except for the redirect set-up, which I'm having some problems with.

I've followed the instructions they have here:

http://www.dudamobile.com//redirect/drupal

I've created a new CNAME record, I've created the block for Duda, I've put in the header, and just for the URL we're trying to set it up for, and I've had no luck.

Does anyone know what's going on here and how to fix it? I called Duda support, and they had no idea what was going on.
