Hi.

I have a function that builds and evaluates an array formula SUM(IF based
on
a number of arguments. Some of these arguments are string values that may
have "" within them.

For example, I might have an item number description (one of the
arguments)
that looks like this: "Left side "H" Bracket".

The function works fine for every item except items with this type of
description. I'd like to avoid requiring users to remove the "" in the
description if possible.

Can anyone help me out?

Thanks!
