help please - complex countif, etc. functions
 

hi all,
I'm trying to make a monthly summary sheet of inventory but don't know how
to fit multiple criteria within a statement. For one product my first column
of data is the month # (1, 2, 3..), second column is part type (type a, type
b, type c, ...). On my summary worksheet for this product I list the part
types in consecutive rows and I'd like to have a formula that links the
summary worksheet to my inventory sheet so that when I type in a specific
month I'm interested in, the number of type a, type b, and type c parts used
during that month will display.
Example Inventory sheet:
Month Type
1 a
1 a
1 b
2 a
3 a
3 c

Example Summary sheet:
Type specific month in cell C1: (e.g. 1)

#type a: 2
#type b: 1
#type c: 0

Please respond with example formulas.
Thanks in advance.

in the cell next to the part number a enter
=sumproduct(--(monthrange=$C$1),--(typerange = $A2))
(or what ever column the summry types are listed)
