Mapping DNS for Custom URL

Mapping DNS for Custom URL

Hello, 

      I have set up my domain account, created my custom sub-domain, and tried to map my DNS.  My domain is hosted by Bluehost and this is how I attempted to map the DNS. Let me know if this is wrong:

1. Went into DNS zone editor.
2. Added DNS record:

      Host Record: mysubdomain.mydomain.com
      Type: CNAME
      Points To: customer-creator.zoho.com

3. Waited 24 hours and tried to go to mysubdomain.mydomain.com, but it only brought me to mydomain.com.

      Am I doing something wrong?  Will this be the url of my application?  I would like to remove my admin name from the link to my application...is this possible?  

Thank you, 
Mike
