How to set the Value of a Record Set in Amazon route 53

I'm trying to configure a custom domain using Amazon route 53, using these instructions provided by Amazon. For the "Value" field (see image below), it says I have to insert a string that contains the information required by the selected type, but it doesn't say what type I have to enter, and what that value would be. In the image below, it shows the default A-LPv4 address, but I changed it to CNAME and then entered my domain name example.com (error) and www.example.com

In both cases, the error said

RRSet of type CNAME with DNS name example.com. is not permitted at apex in zone example.com

I can't leave that field blank either. How do you configure this section?

Note, the example shown in the image appears to use ip address, but I'm not sure which ones you're supposed to use. These numbers (from the Delegation Set)are not permitted format 

ns-1XXX.awsdns-XX.co.uk
ns-3XX.awsdns-XX.com
ns-5XX.awsdns-XX.net
ns-1XXX.awsdns-XX.org

enter image description here

The root (example.com) cannot be a CNAME because it breaks RFC 1034, which states

If a CNAME RR is present at a node, no other data should be present; this ensures that the data for a canonical name and its aliases cannot be different.

However, Route53 provides a proprietary extension known as an Alias resource record that allows this. Choose A record for the Type, choose the Yes radio button next to Alias, then choose an ELB or another record from the same zone as the value.
