Hi,

I'm seeing a problem with the WORKDAY function.  Here is the scenario:

Cell c6:  9/24/2009 (A Thursday)

Cell d6:  2

Cell e6:  9/28/2009  (A Monday.  This will be my holiday)

Cell c7:  =WORKDAY(C6;D6;E6)

The result in c7 is "#Invalid Formula"   The result is the same when d6 is any of 2, 3, or 4.  For all other positive values in d6, the result in c7 is as expected.

Can anyone else duplicate this?  Is this a bug, or a user error?

Thanks.
