Countif formula in excel 2003

[NRMDU]

How to use countif in Excel 2003, for multiple range and criteria ?
Can 'Nested ifs' be used? If so, a sample of such ifs

Thank You in anticipation ...

No, use SUMPRODUCT

=SUMPRODUCT(--(rng1="some value"),--(rng2=numericvalue),rng_to_sum)

See http://www.xldynamic.com/source/xld.sumproduct.html for a detailed treatise
