Search Function - File Handling

Niscuit (17)
So I'm trying to add a search function to this. It isn't running, can anyone give me some pointers? Some bugs I get (initially speaking are):

Line 210: Initializer before 'string'
Line 215: 'fin' does not name type
Line 217: expected constructor, deconstructor or type conversion before '{'
Line 219 expected unqualified-id before 'if'
Thank you.

You are missing enclosing braces for your searchAlbum() function.
