I have never encountered this error, but can take a wild guess.
1) The nameservers data you entered is incorrect
2) You have to wait some time for the nameserver changes to take effect - it usually takes up to 48 hours

Yea, I went to the library to get some books and when I came back and tried it agian, my site came up.

Its working exactly the way I wanted it to now. Thanks for the help.
