range("a1").formula= _
"=SUMPRODUCT((A2:A500=""string_a"")*(n2:n500=""str ing_2""))"

I'm struggling to get to grips with array formula and don't have much
time
left and so I am asking for your help to programatically enter a fomula
that will count
the cells in Range(A2:A500) that contain String_A whose corresponding
cell
in Range(N2:N500) contains String_B

My grateful thanks in advance for any help
