My best guess:

Try putting ( ) around some arguments like this:

=SUM((A1,D27,D99,D1071),(AA48,X222,Y19))

Each set of ( ) is 1 argument.

I am trying to sum a group of numbers and keep getting this message: "more
arguments have been specified for this function than are allowed in the
current file format" How can I correct this?
