Why is this calling a "non-static member function" error?

I'm creating a texted based adventure game c++
Here is the code:

#include <iostream>
#include <string>
#include <cmath>
#include <stdlib.h>
#include <random>
#include <ctime>
#include <ctype.h>
#include "bits/stdc++.h"

using namespace std;

        int d6_5;
        int d6_6;
        double pi = 2 * acos(0.0);
        string playerClass;

            player1.charisma++;
            
    }
    */

}

This seems fine in my eyes but once ran it comes up with this error:

main.cpp: In member function ‘void Player::statAssign()’:
main.cpp:38:21: warning: variable ‘d6’ set but not used [-Wunused-but-set-variable]
