Class and vecors, writing CD collection program

momma14 (2)
I'm writing a code that keeps track of a CD collection, however I've run into some issues with my coding. I am getting errors that "left of the ' ' must have a class/struct/union. But I've declared my class? Any help appreciated

Also, if you could provide enough code in order to us to compile it and receive the same error messages that you are getting, that would be great.

Something I noticed while I was skimming.
On line 92, you are calling addSong(), but that's not a member of the std::string class. Perhaps, what you meant to do, was to have the collection vector be a vector of CDs?
