[NON] Issue was I couldn’t get Lesson 7 Practice 2 to work properly, after re-doing the lesson.
It turns out I was not clicking on indicate in the spot shown below. I was simply “indicating” by clicking elsewhere on the screen, which is wrong. Please see below:
After clicking on indicate (which doesn’t show up as a link on my Win7 64-bit system but can certainly be clicked), I was able to select a region surrounding “Sales”, just to the right of “Cost Center” in the graphic above. This makes the dropdown both a) drop down and b) stay that way.
I could then finish the exercise.
