AWS Route53: how do I add a subdomain?

Question

I am very new to AWS and networking. I did the following, which worked perfectly:

1. Registered a domain name " eyecloud.click " on Route53
2. Created an ELB in London region and an ELB in Sydney region .
3. Created a latency route policy, so that Australia traffic will go to the Sydney ELB , while Europe traffic will go to the London ELB .

All working fine. See screenshot:

Now, I would like to create a new routing, so that sales .eyecloud.click will always go to the London ELB . This is how I did it:

But it doesn't work. When I type " http://sales.eyecloud.click/ " in my browser, I got following error message:

This site can’t be reached
sales.eyecloud.click’s server DNS address could not be found.

What went wrong?

Depending on the TTL set for the overall domain, changes need time to propagate. Mostly root domains have TTL bigger than 12 hours.
