trouble with inheritance(inital problem solved)

tdigdug (36)
I know its been a while since I had a problem, but this chapter has been kicking my butt. I got the program to compile. The data for fist printreport is fine. The data for the second one is is coming out wrong. It appeares to add all of the salary and spitting it out as the same for each data in the second part. Also none of the calculation looks to be no being processed. Anyone Please, give a nudge in the right direction. Your help is appreciated.
Also on line 54, I want to / yearsal by 52 to get gp but when I write yearsal/52=gp I get a lvaule error if that helps.

Believe it or not I solved the issue but not sure if that was right way of doing it. All I know was it works now. Here is the code I changed to make it work please somebody let me know if this was the right way or if there is a better way.

void salary::yearsalgp(){
  hw=40;
  hr=(yearsal/52)/40;
  rgp=hr*40;
  gp=rgp+otp;
  oth=0;
  otp=0;
  }

Now that I have what isee as the hard step time to make it better.
