I am trying to figure out how to do the following. I am trying to get a sum
of numbers in a column, but the numbers need to fit certain criteria. For
example;

I have 500 numbers in a column ranging from 1 to 130
I need the sum of only the numbers between 40 and 60.

I figure that this involves the sum function and some type of "if" and "and"
statement, but i'm not sure how to word this. Could someone Please help!
