group

[Tom <coffindvm@xxxxxxxxxxxx>]

I would like to set up a group and an alias for that group.  I read the manual 
and the wiki and the recent post and still to dumb to figure it out.
I want the group name to be fargo. I would like the alias to be fargo if the 
group name and alias can be the same.

The email addreses are daughter@xxxxxxxxx,soninlaw@xxxxxxxxx

In .muttrc I put group -group fargo -addr daughter@xxxxxxxxx,soninlaw@xxxxxxxxx

In my alias file whose name is addressbook.txt I put
alias -group fargo

I have tried  numerous other ways but none work.
Mutt says my .muttrc has error  and  address.txt has error.

Can someone put this information in correct order ?

Thanks
Tom
