I'm using Excel 2003 SP3. I have a need to use the WORKDAY function.
Microsoft suggests it's available to me in my Excel version (http://
office.microsoft.com/en-us/excel/HP052093391033.aspx). However, when I
try to use it I get a #NAME? error and I can't seem to find any
reference to such a function in the app.

=workday(A2,E2) << this is the syntax I'm using

Is this function truly available in my Excel version? If so, what's
with this error?

TIA,
David
