can't make it work

Question

Hi guys,
Can anyone help me.. I can't make this code work.
The third entry overwrites the second entry.. how can I make it go to the next line.
 

 Purchase_details:
 printf("Details of the purchase...");
 if(qty1>0){
  gotoxy(6,4);
  printf("%s",prdnme1);
  gotoxy(26,4);
  printf("%f",unit_price1);
  gotoxy(43,4);
  printf("%d",qty1);
  gotoxy(60,4);
  subtotal1=unit_price1*qty1;
  printf("%f",subtotal1);
  }
 if(qty2>0){
  gotoxy(6,6);
  printf("%s",prdnme2);
  gotoxy(26,6);
  printf("%f",unit_price2);
  gotoxy(43,6);
  printf("%d",qty2);
  gotoxy(60,6);
  subtotal2=unit_price2*qty2;
  printf("%f",subtotal2);
  }
 if(qty3>0){
  gotoxy(6,8);
  printf("%s",prdnme3);
  gotoxy(26,8);
  printf("%f",unit_price3);
  gotoxy(43,8);
  printf("%d",qty3);
  gotoxy(60,8);
  printf("%f",unit_price3*qty3);
  }

 
THanks..
