Amazon Route 53 Name Doesn't Resolve to Endpoint

This is the first time AWS for anything for me so I'm a complete newbie to this subject.

I registered a name with Route 53 and am using S3 using the static website settings there. I followed AWS's tutorial on setting up a static website from the Route 53 side (to the best of my knowledge). Currently, if I put mydomain.com into the browser url it will give me DNS_PROBE_FINISHED_NXDOMAIN or some similar "site not found" type error. When I check with whois, the domain shows up as registered. If I ping mydomain.com I get "unknown host". If I ping the S3 endpoint of mydomain.com.s3-website-us-west-2.amazonaws.com it gives proper results. Also, if I put in mydomain.com.s3-website-us-west-2.amazonaws.com into a browser it redirects to mydomain.com like it should.

What am I doing wrong? Thanks in advance.
