I created my Zoho account today. I am attempting to verify I own the Domain hroberthuke.com using the CNAME method. 

Following the instructions for Network Solutions (the domain manager), I was able to successfully navigate to the Add/Edit Host Aliases stage. The instructions provided by Zoho do not indicate whether I should keep the existing mail and SMTP aliases. 

Assuming I should keep them, I moved on to adding the zb******** alias provided by Zoho. Step #9 of the instructions says to "Select 'Other Host'". Unfortunately, that is not an option. There is a drop down box with the following to select from for the Host name: @ none - mail - smtp - www.

Any information you can provide to complete the verification process would be appreciated.
