How to sum between to specific dates 
Hi!

I´m trying to calculate values from two columns within each month.

For example

A                         B               C          Months
--------------------------------------------------------------------
2013-06-01          150                          June: 240
2013-06-05          275                          July: 45
2013-06-27                          185          August: -10
2013-07-01                          75
2013-07-20         120
2013-08-01         50
2013-08-18                         25
2013-08-25                         35

So what i'm trying to do is sum column B minus column C for each month with a formula and I can't get it right using SUMif.
Anyone who can help?

Thanks in advance.
