Can you give an example? Most empty spaces of use in formulas have quotes
around them, like
=IF(A1="","none",C1)

Apparently you can get away with formulas like:

=SUM( B1:B15 )

but the first paren must be right up against the function (sum).

Can someone explain to me or point me to a good site that explains how an
empty space is used in formulas and what it means? Thank you.
