Creating New Account

Hi

I have recently had a new server and have, to what I believe correctly setup the nameservers etc on it.

I opted for my own private nameservers, and followed the instructions on hostinglife.com to set them up.

My problem is, when I goto setup a new account in WHM, it says please setup nameservers in account setup before ontinuing.

My questions are:

Has anyone had this problem?

Is it relating to the DNS not propegating correctly yet... Would I have to wait for the DNS to update before WHM would accept my new nameservers?

Thanks
