F7 Silly question about system-config-samba

[antonio montagnani]

If I am running samba with the following samba.conf file:

# Samba config file created using SWAT
# from 0.0.0.0 (0.0.0.0)
# Date: 2007/06/18 15:40:35

[global]
	server string = Samba Server
	update encrypted = Yes
	log file = /var/log/samba/%m.log
	max log size = 50
	dns proxy = No
	ldap ssl = no
	path = /home/antonio/Documenti
	writeable = yes
	guest ok = yes
	cups options = raw
;	workgroup = workgroup
	username map = /etc/samba/smbusers
;	workgroup = workgroup
;	security = user
;	encrypt passwords = yes
;	guest account = nobody
;	security = user
;	encrypt passwords = yes
;	guest account = nobody

[homes]
	comment = Home Directories

[printers]
	comment = All Printers
	path = /usr/spool/samba
;	writeable = no
;	guest ok = No
	printable = Yes
	browseable = No

[myshare]
	comment = condivisione
	path = /home/antonio/shared
	valid users = antonio
	create mask = 0765
	writeable = yes
;	browseable = yes

[musica]
	comment = directory musica
	path = /home/antonio/musica
;	writeable = no
;	browseable = yes
	valid users = antonio

I should see workgroup in  the following window, instead I see a blank
line where mygroup is...why??

Another question: what does a ; mean in front of a line ??
