Of course,

True is caused when the PO does not change dates at all.

False is if the date has changed.

As I run this report once per week, my goal is to see the life time of a PO# if it ever has the dates changed when I export the data from Quickbooks. I am trying to find the % of POs that are being changed during their lifetime. So I have associated weeks of data in this overall spreadsheet to show me each week and if the data ever = FALSE. If the data does ever = FALSE then the PO#, no matter how many times it has been in the spreadsheet will always = False. I only want the data to default to answer as the PO has change there for it answers false only once.

I hope that helped explain it.
