I'm looking for a formula that will Count the # of months of the duration of
a project (row). In this example, I want a formula to calculate the # of
months from beg to end months. This example below (Row 2) is assuming the
project started in JAN and ended in Jun. So the result should be 6 months. So
I want to count the months with zeroes in between the beg and end months. In
my spreadsheet, I have columns going out to Dec-08. So there are 0's in every
month after Jun in Row 2 in my spreadsheet. Is there COUNT or maybe a
SUMPRODUCT formula that will achieve this? Thanks!!
