Hi,

I have a problem with the formular: NETWORKDAYS(C4,D4). It
says that this formular contains unrecognized text.


Column: C D E

Ex: DATE POSTED DATE FILLED DAYS OPEN
2/5/2004 0:00 2/9/2004 0:00 =NETWORKDAYS(C4,D4)

It shows #NAME error in the cell E4 which contains the
formular =NETWORKDAYS(C4,D4).

Please tell me how to fix it.
