Okay, this is an extension of the Neither “A” Nor “B” sum problem we discussed few days back.
Imagine you have a table named mydata with a few columns and a stop list named stop.list as shown below.

How would you calculate,
- Sum of Hours for all activities excluding those in stop list?
- Sum of all Regular hours for activities not in stop list?
So go ahead and post your answers in the comments.
I am waiting…
Want more challenges?
Attempt below home work problems as well.
