Hello all

I use the following function on my laptop and it works beautifully:

=SUMPRODUCT(--('Daily Reading Master
Log'!B$3:B$375=DATEVALUE("01/01")),--('Daily Reading Master
Log'!B$3:B$375<=DATEVALUE("31/01")),'Daily Reading Master Log'!BM$3:BM$375)

When i send the workbook to my the user, all he sees is VALUE! in the boxes
where this function is used.

Why?
How can i fix this?
