It's never desperately helpful to say "it returns an error message". Youre
more likely to get help if you tell the group WHAT error message you're
getting.

Why do you suggest a problem with parenthseses? They look to me as if they
match, and Excel doesn't report an error for me.

The most likely problem of which I could think is that perhaps your regional
settings expect a semi-colon as a list separator, whereas the formula as
quoted includes commas. Have you checked your regional settings? Have you
tried changing commas to semi-colons (or whatever your settings are
expecting)?

Thanks for the reply Gary
I think there is something wrong with the parenthesis with this formula as
it returns an error message.
Any further suggestions?
