You need a minimum screen resolution of about 700 pixels width to see our exercises.

Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
Create a new workbook, and import the tblPurchase and tblProduct tables into a PowerPivot data model.
Create a measure called NotAnOtter in the purchases table to show total quantity sold for all purchases where the animal name isn't Otter. Here's what you might get when you show this:
Initially all the figures might look the same.
Solve the problem (that the measure shows the same value for each row) by including the VALUES function in your measure to get:
The two columns should now give the same values for everything but otters.
If you'd already done this, you can just look smug!
Save this workbook as Otter Spotter, then close it down.
