your own nameserver on domainzero

Has anyone try putting in your own hosts nameserver ? cause when I put the nameserver I get an error..

I've done it without any problems! :)

what did you put? Ip or the nameserver?

I put nameserver. Did you allow 24-48 hours for your ISP records to update?

its been a week! I e-mail them they just say that they are having problems.. I guess they don't care. when I enter the namesever it say that the dns list is not found... and I can't modify the nameserver.. evertime i try i get the message dns list not found.
