COUNTIFS between two dates over multiple columns with additional criteria

I'm trying to count the total number of various statuses that occur between two dates.

Please see attached.

I've tried the formula =COUNTIFS($C$2:$G$11,">="&K$1,$C$2:$G$11,"<"&L$1,$B$2:$B$11,K2)

But this only seems to work for one column of dates or when you exclude the last criteria.

Any help appreciated.

COUNTIFS requires identically sized arrays -- so you cannot have C2:G11 (10x5) and B2:B11 (10x1)

You would need to switch to SUMPRODUCT, e.g.:

=SUMPRODUCT(($C$2:$G$11>=K$1)*($C$2:$G$11<L$1)*($B$2:$B$11=$K2))

Many thanks
