Error Traps.....

Published:

.....work. The trap that was established by Phase II caught two offsetting errors in Phase I. In all likelihood, these errors would have been statistically insignificant with regards to the overall project but the fact that they were caught gives credence to the effectiveness of the quality assurance portion that was built into this project.

And, speaking of Phase I, that part is virtually complete. The web pages are built and uploaded, the paperwork is ready to go. The only thing left to do is a QA check of the web pages. Phase II might be done before the end of the year, but I might be overly optimistic here.

I noticed long ago that as my code got more complex, I could find errors that had been "hidden" in simpler versions.

jarasan -

The data for Phases I and II is the same, but the spreadsheet formulas were and are manipulated to yield different subtotals. It was during the Phase II subtotal examination that the offsetting errors in Phase I were caught.

FYI, there are two spreadsheets per phase, each with approximately 110,000 cells where data is entered.
