Help setting up subdomain

[lordv2500]

I've got an account with chromehost. Chrome gave me two nameservers to use: ns1.u4w.com and ns2.u4w.com.
How do I set up my subdomain to use them? Here's what I did:

But it's not working. What am I doing wrong?

You gotta put those vaules in "Change your Nameservers" or somthing

[lordv2500]

That's what that is. That page appears after I click on "modify NS record.

In that case then - just wait 48 hrsish until the domain propogates and setup your subdomains with chromehost

[lordv2500]

48 hours? You sure? It says that it'll update DNS zones in one hour. Is that something altogether different? At the moment when I enter the subdomain url it just redirects me back to the da.ru main page.

da.ru is unrealiable altogether.. has it worked for you in the past? some isp's it can take 24-48 for (sub)domains to work
