Excell - two conditions count if factors are true when negative nu

[linda]

Formula to count if two conditions. I want to count column b when = "CAS"
and if the number in column J is a negative number.

I have tried =COUNTIF(B7:B21,"=CAS")=SUM(J7:J21,""<0)
but it returns a "false" read.

Column "b" are all words and Column "J" is numbers, but sometimes a negative
number and I only want it to count if it is "0" or Less (negative)

=SUMPRODUCT((B7:B21="CAS")*(J7:J21<0))
