Hi,
I have an excel sheet with two ranges first one is dates the other one
is quantities.
while quantities could be negative.I need to count how many days back
until the quantity is zeroed.
every cell needs to be calculated with above 15 days being equal to one
and below 15 days equals to 0.5
I can't seem to find a way to loop a formula onto a range...

I wrote this formula to calculate the dates
=IF(F7<0,(IF((DATEDIF(F6,G6,"d"))<15,15,30))*(IF(F 7<0,(ABS(F7)))/30),)

the date range is F6:AK6 and quantities is F7:AK7

Thanks
Ofer
