Please help i am getting an error message when i try to complie my program. It gives me this error rror C2664: 'output_calculations' : cannot convert parameter 1 from 'double (double,double)' to 'double' Context does not allow for disambiguation of overloaded function.

I have not the slightest clue what this means please help.

```
#include <iostream>
using namespace std;
void user_input();
double hat_size(double weight, double height);
double jacket_size(double weight, double age, double age2, double height);
double waist_size(double age, double age2, double weight); //(age, age2, weight
void output_calculations(double hat_size, double jacket_size, double waist_size);
bool restart();
int main ()
{
user_input();
return 0;
}
