COUNTIFS With Date Range

Hey,

I need help with a COUNTIFS function (I think that will be the best function to use at least).

I have a two columns of data, column one is dates (mm/dd/yyyy) and column two is states (AK, MA, MI, etc). I need a way to count how many times a states comes up for a certain month. For example, I need to know how many times MA appears through the dates 1/1/2007 and 1/31/2007.

Here's what I have so far. It works but I can only specify one date. Any help you can provide would be greatly appreciated.

=COUNTIFS('SHEET NAME'!D:D, "1/5/2007", 'SHEET NAME'!E:E, "MA")
