[Samba] Sharing Issues

[cH4os]

Greetings All,

Having a Sharing Violation issue, on one of my shares (SPECWORKS) 
running a Paradox Database program from this share...

Could someone verify this for me?

[specworks]
    browseable = yes
    comment = SpecWorks Data
    path = /home/specworks
    writeable = yes
    valid users = steven tim gary dennis larry david
    security mask = 0777
    force security mode = 0
    directory security mask = 0777
    force directory security mode = 0

BASICALLY, I need these users FULL access to this share & Directory
I have the OWNER as me, and the GROUP as SPECWORKS, I have all of the 
users members of the SPECWORKS group...

Thanks
