How can I avoid this warning when working with blank fields? I am trying to get the count of lines with successful cases (1,1) and lines with failed cases (1,2). 
Data Structure
1,1,,,,
1,2,,,,
3,4,1,1,,
1,1,1,1,,
5,6,3,4,1,2
1,1,,,,
1,1,1,1,1,1

  #Success & Fail
  if((($f[1]==1)&&($f[2]==1))||(($f[3]==1)&&($f[4]==1))||(($f[5]==1)&&
+($f[6]==1)))   {
    $success = 1;
  }else{
    $success = 0;
  }

  if((($f[1]==1)&&($f[2]==2))||(($f[3]==1)&&($f[4]==2))||(($f[5]==1)&&
+($f[6]==2)))  {
    $fail = 1;
  }else{
    $fail = 0;
  }
