Write the function double compute_npay(double gpay) that receives an employee's gross pay using the value parameter gpay, computes the net pay and returns it. the net pay is the gross pay - the tax deduction. To compute the net pay, it first calls compute_taxes() to compute the tax deduction.

The error tells you exactly what the problem is are where it is. What don't you understand about it?

wow im sorry, i just dont know whats wrong with it, sorry

[Michaela Elise]

the compute taxes function takes an argument double gpay
on line 16 you call compute_taxes();
By only using () and nothing inside of the parenthesis, you are passing no arguments.
just because "gpay" is visible to compute_npay, does not mean that comput_taxes sees it.
you need to compute_taxes(gpay);

Also your function does not return a value

double compute_taxes(double gpay)
{
      // double gross; //Im guessing you mean gpay, but do not redefine it
       if (gpay <= 1000)
          return  gpay * 0.5;
       else if(gpay < 1500)
            return  gpay * 0.6;
       else
           return gpay * 0.7;
}

double compute_npay(double gpay)
{
       //double gross;  Unused
       double npay, td;   
       td = compute_taxes(gpay);
       npay = gpay - td;
       return npay; //Probably what you need to do here
