Excel 2007 : Need help with some formula's

[seaturtle777]

I am currently using this formula and it is working correctly:

=SUMIF('Sales Pipeline Management.xlsx'!SaleMade,">="&DATE(2012,1,1),'Sales Pipeline Management.xlsx'!CommWritten)

However I want to add a second date range to segment the info by calendar quarter. How do I add the second criteria?
