-Hello,
I want to put together a table with dates spanning across several weeks.
I've been trying to use the weeknum function to count the dates that fall
within the same calendar week and total them together. I'm getting an error
(#NAME) when using this formula. I tried downloading the excel add-in too but
it still doesn not work.
Can someone please help?
Thanks in advance,
Nelly
