Verifying a domain

Verifying a domain

Hello,

Trying to transfer hosting of my domain, Landform.co.uk, to Zoho. After discussions with my current hosting provider they think their responsibilities are complete but clicking the "Verify by CNAME" button on the Domain Setup page has no effect. The settings my current provider has given are:

DNS Records
ftp A   62.44.77.153
@ MX 10 mx.zoho.com
@ MX 20 mx2.zoho.com
www A   62.44.77.153
zb******** CNAME   zmverify.zoho.com

The zb code is the one from the Domain Setup page. My DNS manager is Register.com. Any contact with them has to be through my current hosting provider.

Any help would be much appreciated.

Regards

Nick
