problem with constructors and classes

[armen_shlang]

I have a class like this:

#include "History.h"
class arena
{
 public:
   arena(some arguments)
    : m_history(int num1, int num2) {};

 private:
    History m_hisory;
}

and history class is basically something like this:

//history.h
class history
{
 public:
    history(int num1, int num2){row=num1; col = num2;}
private:
    int row, col;
}

the compiler says that i can't have 2 argument for m_history, in the arena constructors member initialization list. How can i overcome this problem?
