Default Unique numbers if between dates

I have been using the following formula to add the number of unique numbers
in column A.
=SUM(IF(FREQUENCY(CaseData!A:A,CaseData!A:A)0,1))

HOWEVER,

Now I want to only count unique numbers in column A, only if column C is
between 1/1/2005 and 3/31/2005 (or any 2 dates for that matter).

EXAMPLE:

A C
5123456 1/1/2005
5123457 1/5/2005
5123457 1/5/2005
5123457 3/7/2009

The result should be 2 - because there are 2 unique numbers in A while C is
between 1/1/2005 adn 3/31/05.

=SUM(--(FREQUENCY(IF((C1:C100=--"2005-01-01")*(C1:C100<=--"2005-01-31"),MAT
CH(A1:A100,A1:A100,0)),ROW(INDIRECT("1:"&ROWS(A1:A 100))))0))

as an aarry formula, so commit with Ctrl-Shift-Enter

Try the following formulas that need to be confirmed with
CONTROL+SHIFT+ENTER...

=SUM(IF(FREQUENCY(IF((C1:C4="1/1/2005"+0)*(C1:C4<="3/31/2005"+0),A1:A4),
IF((C1:C4="1/1/2005"+0)*(C1:C4<="3/31/2005"),A1:A4))0,1))

or

=SUM(IF(FREQUENCY(IF((C1:C4=E1)*(C1:C4<=F1),A1:A4 ),IF((C1:C4=E1)*(C1:C4
<=F1),A1:A4))0,1))

....where E1 contains your start date, and F1 contains your end date.

Hope this helps!

Forgot to coerce the second ending date for the first formula...

=SUM(IF(FREQUENCY(IF((C1:C4="1/1/2005"+0)*(C1:C4<="3/31/2005"+0),A1:A4),
IF((C1:C4="1/1/2005"+0)*(C1:C4<="3/31/2005"+0),A1:A4))0,1))
