wildcards in sumproduct functions
SUMPRODUCT doesn't accept wildcards.
Try something like this to count cells in A1:A10 that might contain "ABC"
anywhere within the cell:
=SUMPRODUCT((ISNUMBER(SEARCH("ABC",A1:A10))))
Note that case is not factor. ABC is the same as abc.
If in your application case *is* a factor then replace SEARCH with FIND.
Using FIND, ABC is not the same as abc.

I would prefer to use a wildcard for text criteria in sumproduct counting
and
adding equations. I have tried versions of "*ABC*" and get false values.
