In the main source file, this is between lines 27 and 34. So let me cut and leave a to do comment as usual. Now let's adapt the code in records.cpp. The first change is in line 90. Notice that the type of GRD is referenced to grade. Now since we are inside a getter function that enforces cons correctness, this type is in conflict.
