Name server on subdomain behind Amazon Route 53

I have a linode server with a name server running on it. I have my domain: example.com registered through GoDaddy. And the name servers set to Amazons, I am using Amazon Route 53 to manage it. I want a subdomain (ln.example.com) to point to my linode server that houses a name server for itself. I have already tried adding a and ns records that point to my linode ip and ns records (ns0.ln.example.com and ns1.ln.example.com).

note: I also have a reverse DNS record setup on linode with ln.example.com connected to MY_IP_ADDR_HERE

Amazon Record Sets for example.com:
