It took me a couple of tries to get it right, but if you take it slow one step at a time it will work.
Now #8 is very important because not every one types in www. before a domain name so be sure enter your A-records. You will have to repeat step 9 four times.
This part is specific to go daddy as it the service I am familiar with.
I hope this helped, if not I am truly sorry. When I get stumped I always call godaddy and they always walk me through it step by step and if you get a really nice person they might even do it for you :)
Good Luck!
