Appendix A and the appropriate chapter.
You requested a tolerance to which the algorithm cannot
return an accurate result.
You referenced a variable that is not currently defined. For
example, you referenced a stat variable when there is no
current calculation because a list has been edited, or you
referenced a variable when the variable is not valid for the
current calculation, such as
