Countif between two dates

[Guest]

I have the following formular:

=IF($B5002="","",COUNTIF(MAIN!$B$10:$B$5000,"" &$B5002 & ""))
Column A is the date
Column B is the unit

How do I modify it to count between two dates that are in cells Sheet2 P3
and R3

Thank you

adapt to suit
=sumproduct((a2:a22>b1)*(a2:a22<=b2))

=IF($B5002="","",SUMPRODUCT(--(Main!$A$10:$A$5000>=Sheet2!P3),--(Main!$A$10:$A$5000<=Sheet2!R3),--(Main!$B$10:$B$5000=$B5002)))
