=sumproduct(--isnumber(a2:a500))

Hello, all:

I have a column of about 500 cells, some of which contain numbers, some
contain blanks, and some contain the word "none". I want to put a formula
in
the cell at the top of the colum which counts ONLY those cells which
contain
numbers.

Is there a specific function which will recognize only numbers? Failing
that, I assume a COUNTIF is in order.

I tried this:

=COUNTIF(A2:A500,AND("<""","<none"))

but it yields a zero. I've also tried variations moving around and
eliminating the double quotes but I can't get it to work.

Any suggestions? Help is appreciated. Thanks,
MARTY
