album name want to omit some part

i have album name as
how can get the album name as
i want to get the album name without the comment part starting with a dashsign.

at last i found the way out. thanks for the developers of this soft. this is such a wonderful soft. names of any number of files are converted as per our wish. here is the example for the novice like me.
original album name>album name-where u get it from.com
you want the album name as>album name
then actions>guess values
source format>%album%
guessing pattern>%album%-%comments%
(for this the comments filed must be empty)
then delete the comments field by selecting blank. done.

thanks again . have a nice day.

You can also use %album%-%dummy% to omit the last part.

thanks a lot for the suggestion. have a nice day
