I tried to find a solution by searching posts, but had no luck understanding
them. Here is sample table and then my question:

A B C D
0 1 1 Tuesday
0 0 0 Monday
1 0 1 Monday
0 1 0 Friday

I want to add the values in column A where column D="Monday"

I am guessing it would be similar when counting the number of "1"s in column
A when D="Monday

Any help with this would be greatly appreciated.
