Can't create a CIFS share in iManager with unc path to share

Trying to create a new share in iManager.
ERROR  The given volume name could not be found on the specified server.
First time setting up a CIFS share.

Use the syntax:   :\
example:  vol1:\data\forms\
(make sure you include the backslash after the path)

You can also create the shares from the server console by typing:

cifs share add :\<# of connections allowed>'comment'  (in single brackets)

Example:  to create a share to a folder called forms type:
cifs share add data:\forms\ 25 'my favorite files'
To verify the share was created, at the server console type: cifs share

Trying to use a UNC path that would not work.
