We have a new Excel Challenge folks!

I know our friends in US are away celebrating Memorial Day weekend. But that should not leave rest of us from fun. So, we have a new Excel Challenge. This time, you need to make a chart, to visualize product sales data.

And what more, one lucky person could get an Amazon Kindle Reading Device (Wi-fi version) by making the chart.

We have a new series on chandoo.org. – Excel Challenges. From now, every 1-2 months, I will post an interesting Excel Challenge. These are tricky problems for which elegant solutions should be found. To keep the challenges exciting, we will have a small prize for a winner (if more people answer correctly, we pick one randomly)

We have an Excel Table, with the following data (snapshot above). You need to write formulas to display Ok or Not Ok in the adjacent column based on the following criteria:

1. Display Ok if the scheduling dates for that row do not overlap with remaining scheduling dates for that machine
2. Display Not Ok otherwise.
