Samba Config Problem - why does one work and the other not?

I have two different samba shares configured.

Can someone PLEASE tell me my one works exactly as expected (e.g. limits access to the requisite group and give them complete access) while the other one allows EVERYONE view privileges and no one has write/modify privs?

I am sure I missed something stupid.... but I am too tired to figure it out if I did.


1.
[SHAREGROUP1]
writeable = yes
write list = @sharegroup
force security mode = 111
create mask = 770
directory mask = 770
comment = Storage space for sharegroup files
user = @sharegroup
path = /data/common/ShareGroup

2.
[SHAREGROUP2]
writeable = yes
write list = @sharegroup
force security mode = 111
create mask = 770
directory mask = 770
comment = sharegroup's Drive
user = @sharegroup
path = /mnt/sharegroup
