newbie String question

[hebes_99]

I am having a problem passing a string ref into a class function....

in Header file.....

#include <string>

class Process
{
public:
Process();
virtual ~Process();
int Process::GetBuno(const string& buno);
};



in Main file

#include "stdafx.h"
#include "Process.h"

int Process::GetBuno(const string& buno)
{

// some code

return buno;

}






When compiled... I get ..
(19) : error C2143: syntax error : missing ',' before '&'
(19) : error C2059: syntax error : '&'


Thoughts?
