What Does Excel Tell You When You Actually Do This?

The self reference problem is when that bottom cell, the total cell, which is supposed to contain the answer, is itself referenced in the question or the tally of the total. This error doesn't just exist in excel. It exists in every single symbolic system, whether it's an excel spread sheet or some computer code. You know, you can actually cause the computer to crash or to malfunction by finding this sort of self reference error.
