Answer

If a MultiQuant software results table returns an area ratio of N/A, then there may be an issue with the quantitation method. Namely, an internal standard may have been designated--but not assigned--to the analyte in question. Alternately, if the internal standard is not be integrated for some reason (due to a shift in retention time, for example), this may also cause the area ratio to show as N/A.
