Configure custom nameservers in DirectAdmin

I have a VPS through DirectAdmin and I'm having difficulty setting up custom nameservers and getting my domain to work.? I just need someone to take a look at the settings and change them if they are required. **You will be paid the $10 + a $15 bonus only when my domain successfully propagates.**? I can register the custom nameservers at my registrar.? I know how to do that.? I just need the settings checked in DirectAdmin.? Thanks.
