Samba Configuration Problem

[CrAzY12]

I am setting up my first samba server! and the document from Ubuntu is great but I received a few errors once I ran testparm
Please see Attachment 1: Samba Errors and Attachment 2: Host Allow (from the smb.conf file)

Now the errors are very straight forward and as I looked closer into my smb.conf file, I can not see the mistake I made in editing my host allow & host deny config line (Attchment 2: host allow). I would think this would be a simple solution but I am still learning.

Apparently, it should be hosts and not host.
