Also, he's working with French version, but I think the translation is fairly
obvious.

One big thing - as he mentioned, it is an 'array formula' and must be
finished up with [Ctrl]+[Shift]+[Enter] instead of just the [Enter] key. And
if you have to edit the formula(s), you have to end them in that same way for
them to continue to work.

I must be doing something wrong because I can't seem to get this to pull
anything. Why is there are reference to A7 and a7 has nothing in it?

Thank you

For C19, try the following array formula :
(validate with Ctrl+Shift+Enter)
=SUM(IF(MATCH(A7,$A$7:$A$12,0)=MATCH($A$1:$A$4,$A $7:$A$12,0),1,0)*IF(MATCH(A7,$A$7:$A$12,0)<=MATCH( $B$1:$B$4,$A$7:$A$12,0),1,0)*$C$1:$C$4)
For D19 :
=SOMME(SI(EQUIV(A7;$A$7:$A$12;0)=EQUIV($A$1:$A$4; $A$7:$A$12;0);1;0)*SI(EQUIV(A7;$A$7:$A$12;0)<=EQUI V($B$1:$B$4;$A$7:$A$12;0);1;0)*$D$1:$D$4)
Drag down as needed.

I am looking for a way to formulate the data in C19-24 as well as D19-24
using the information in A,B,C and D 1-4. Please note it is counting the
data including the months given and the months between. Can someone please
help with a
formula.

Thank you
