ive been playing around with sumproduct and I had it working. but now for some reason I cant get it to Calculate fully.
Ive attached a file to help.
I basically need to work out how many times between 09/10/2013 and 15/11/2013 that Tony has "resolved" his issues. (based on date received)
.
I've converted to a range to help with the test.
I really cant see where I'm going Wrong
