Multiple campaigns

Multiple campaigns

I would like to add a subscriber from my 'master list' to some of my other lists.  How do I go about doing this?  

I went to 
Contacts
Selected the name(s)
Selected 'copy to list'
Selected the list(s) with check-marks
Tried to Save but got an error message (pop-up)

I thought this would be the way to get one name on multiple list but is there another way or something I am not doing correctly?
