Information retrieval functions

Hi,
I'm new here, and a bit of an Excel newbie and would like to learn more but
for starters I have a question about trying to retrieve and sort information
from data in a worksheet.
I work in a laboratory that tests patients for genetic abnormalities and
this information goes into a system that we can pull out the data as a text
file that will go into Excel as a new worksheet.
What I want to do is this: In one column is the type of test and in
another is the date the specimen was received. I want to find out the
number of tests done for a particular month. I know I can do autofilter and
do longwinded counts using that but is there an easier way to do this? Some
sort of function? Would setting up the worksheet that is linked to Microsoft
Access a better way to routinely pull up information??
I'll be asking the boss to send me on a course I think!!
Any help would be appreciated.
cheers
Jasen

If your test types are in Column A, and the corresponding dates are in
Column B,
AND, there is a date for every test, AND *no* date in Column B if Column A
is blank, then you could just count the dates in Column B that match a given
month and year.

Enter a date in C1, and this will count the dates in Column B that match
that month and year in Column B:

=SUMPRODUCT((TEXT(B2:B100,"m/y")=TEXT(C1,"m/y"))*(B2:B100<>""))

Thanks RD, I assume this works to retrieve the numbers on specified dates
for all tests together, but I forgot to add that I want to retrieve the
numbers for "Test A" or "Test B" (for example) not both at the same
time.....sorry. How do you adjust the formula to pull that out? Many
thanks for this.

Enter the test type you're looking to count into C2, and try this:

=SUMPRODUCT((TEXT(B2:B100,"m/y")=TEXT(C1,"m/y"))*(A2:A100=C2))

Thank you, it works great! Spot on.
I will take note of the format of how you did this and apply it elsewhere.
Thanks again,
Jasen
