However, that requires that Sheet3 exists, for example.

I was able to leverage the idea to produce the following, albeit not as
robust as I would like:

=SUMPRODUCT(--(COUNTIF(INDIRECT({"sheet1","sheet2","sheet4"}&"!B 4:B6"),"<=20")))

However, I really want to get COUNTIF out of there. The formula I would
like is something like:

=SUMPRODUCT(--(INDIRECT({"sheet1","sheet2","sheet4"}&"!a4:a6")=A 5),
INDIRECT({"sheet1","sheet2","sheet4"}&"!b4:b6"))

Again, the obvious workaround is:

=SUMIF(Sheet1!A4:A6,A5,Sheet1!B4:B6)
+SUMIF(Sheet2!A4:A6,A5,Sheet2!B4:B6)
+SUMIF(Sheet4!A4:A6,A5,Sheet4!B4:B6)

And I guess that's not bad, if I must enumerate the worksheet names in the
INDIRECT expression.

I was hoping for something tidier and more extensible.

Thanks. That is helpful. However, that requires that Sheet3 exists, for
example. A range of the form Sheet1:Sheet4!B4:B6 works (with SUM) even if
there is no Sheet3.

Try

=SUMPRODUCT(--(COUNTIF(INDIRECT("Sheet"&ROW(INDIRECT("1:4"))&"!B 4:B6"),"<=20")))

When I write SUM(Sheet1:Sheet4!B4:B6), that works.

But if I change the function name to SUMPRODUCT, I get a #REF error.
Copied from the Formula Bar:

=SUMPRODUCT(Sheet1:Sheet4!B4:B6)

And if I use that form of range in a subexpression, I get a #NAME error.
Copied from the Formula Bar:

=SUMPRODUCT(--(sheet1:Sheet4!B4:B6<=20))

Note that Sheet1 is lowercased by Excel. All my changes were made by
successive minimum editing of the original SUM formula.

Is there some way to make this kind of range work with SUMPRODUCT, short
of the obvious, namely breaking this into multiple subexpressions?
