A more concise way of stating this would be to say that: For each line item, I need to count all of the line items (including this on) that _start_ with the same value plus an optional "/".
For example, using pseudo-regex syntax: - A count of all of the lines that start with "Arts$" or "Arts/" - A count of all of the lines that start with "Arts/Animation$" or "Arts/Animation/", etc. I should have led with that, but I'm still feeling out the problem a little bit.
