Okay, that may appear a bit too fast. But the new improved version of our excel formulas e-book, now called “Excel Formula 1” is out today. I have included 25 more formulas and improved the content and layout greatly. The book costs $10 and you can buy it from here. If you want to be sold, visit the sales page here.
We will resume our regular broadcast tomorrow.
PS: Did I tell you all the earlier purchasers of Excel Formula Helper e-book got a free upgrade, oh yeah!

How did you arrive or formula when you ask me who made more sales Jackie or Jamie?? I could not figure the formula out yet??
@Frank
You need to sum up the sales for Jackie and compare them to the sales of Jamie over the same period.
The practical parts depends on how and what data you have and how it is arranged.
But it will either involve a Sum, Sumif, Sumifs or Sumproduct to accummulate the sales for each within a specified date range.
