I have a large table of data that I want to sum, based on 2 criteria.
A small example of table as follows:

Quarter Type Value Resource

Q1 Fire 2,000 John
Q2 Project 1,500 Bob
Q1 Project 2,000 Sam
Q3 Fire 2,000 Louise
Q1 Fire 1,000 Shirley
Q1 Project 5,000 Jill

What I want to do is total up the the value of Fire for Q1.
