member function "Quest::PlayQuest" may not be redeclared outside its class

topman20000 (3)
Thanks for any guidance, Terribly sorry in advance if things look messy or bulky.

I'm trying to invoke a function declared in a separate header file/ defined in corresponding .cpp file to run within my int main(){} before it goes to system("pause"). I want to have some continutity from one quest to the next, based on user input, and I was trying to organize the functions for each next in header files to include them. However I'm getting an error on where it says 

 
 
void Quest:PlayQuest;


Code Description
Error E0392 member function "Quest::PlayQuest" may not be redeclared
outside its class

I've not had much luck wrapping my brain around this one for my particuar case. Any guidance would help at this point.

Making these changes it did compile with the exception of the undefined variables in "main".
