I'm trying to count the number of rows that matches multiple criteria in
multiple ranges. As an example, I want to count the number of rows where
both Column A and Column B have a date between 01-01-05 and 12-31-05. Whe

Column A Column B
01-02-05 12-20-05
01-06-05 02-20-06
05-06-09 03-07-05
01-02-06 01-09-06

So, in this instance, I want it to count only row 1 because both columns
match the criteria.

I've tried a couple of different Countif statements, but I can never get it
to count using the multiple criteria and ranges. Please assist.

Things I've tried:
=Countif(and(A:A,B:B), ""&C1))+countif(and(A:A,B:B), "<"&D1) - - where C1
is equal to 01-01-05 and D1 is 12-31-05
