Server custom name server setting and DNS setting

I am having problem with setting custom name server with my godaddy domain and its giving this error message "Problems with dns setup" I know that I did not able to provide name server on godaddy because godaddy is telling name server is not registered. I need you to check it on my Linux server and Godaddy domain and make it correct. My budget is US$10 for this as this is a task of 10 minutes. Also you have to tell me where and how you made the changes and what was the problem. I will award this project within next 3 hours.
