Can anyone help out.I started a free blog host with and later on I purchased a domain from qservers.net and later host it in GlobalHosting247.com but the problem is that the domain is saying server not found ", please any contribution towards this.

Hello Samdede, it's really not clear what you want to achieve. However, from my understanding, I think you are currently running a hosted blog and NOT Blogger.
.
Based on what you said, I presume GlobalHosting247.com is your current web host and you purchased a domain name from qservers.net. And now trying to visit your blog at GlobalHosting247.com with your registered domain gives you an error.
.
This is probably so because your name servers have not been set or configured. You will need to get the name servers from GlobalHosting247.com and point them to your domain name. Doing this should give you expected results.
.
Anything out of this may be best explained by the next person below me. Cheers.
