Help with setting up a subdomain redirect

Hi:
i'm trying to set up a subdomain called "test.mysite.com" to redirect to another IP. In WHM, I went to "Modify DNS Zone" for mysite.com, and added the A record:

test 14400 IN A 30.30.30.30

where "30.30.30.30" is the destination IP hosting the actual test.mysite.com site. But it's not working- entering "test.mysite.com" goes nowhere.

Thanks for the help.
