I registered a domain by Bluehost. However, I could not set up the domain correctly for Google sites at Bluehost:

Google's instructions
Sign in to your domain hosting service and locate the DNS management page. The location varies by service, but can typically be found under Domain Management or Advanced Settings .
Use the following unique string to create a new CNAME record for the domain.com domain:
googlea0406ece---
Point the CNAME record to:
google.com
- Once you have made the changes, you can verify that the record exists by doing a CNAME lookup for http://googlea0406ece---.domain.com . You can find several web sites to do automated CNAME lookups by searching for CNAME lookup at http://www.google.com
How can you assign a domain to Google Sites which is registered by Bluehost?
