I'm trying to do the following:

When you enter the following function:
=SDSUM(A1:B3,$B$1,B1B2)

I want the third argument in:
Function SDSUM(database, col, criteria)

named criteria, not to return whether B1B2 (True of False), but (just)
the string. However, I don't want to put quotation marks around it
because I want the user to click around in the worksheet to make
selections.

Any way to do this?

Thanks for any ideas.
