Hi,
I see the DNS TXT Record now. Looks like you are trying to verify with the "www" variant and the console seems to prefer verifying the root domain of
http://yourdomainname.org/ first. Try adding the root domain and verifying it. It should be the same verification code, but if not, add another TXT record that the console suggests. If that doesn't work, we can try adding/verifying via the Domain Property option.
Note that the attempt to verify the "www" variant may not work out at all since there is no "A" record for your www subdomain in the DNS settings.
Just curious, are you trying to set the domain to a google sites or blogspot?
