Thanks Chip,

I had tried both with and without the quotation marks before without
success, your confirming the syntax I at least convinced me that my
error was elsewhere and to resolve it. I'm embarassed to say that I
had the formula right (without the quotation marks) but i was
referring to Fiscal 08 - the only fiscal I have that is void of
data.

abashedly grateful,
Andy

Most likely, you don't want the quotes around the 1 in your comparison to
WeekdayAll.

=SUM((DateAll)*(WeekdayAll="1")*(quarter="Q1")*(Fi scal="F2008"))
should bw
