Hello, I have a list of Machines on each Friday that I would like to flag with a number. The latest Friday should have a 2 and each Friday before that should be marked with one less than the last. My data is below.

[TABLE="width: 236"]
<colgroup><col width="90" style="width: 68pt; mso-width-source: userset; mso-width-alt: 3291;"> <col width="45" style="width: 34pt; mso-width-source: userset; mso-width-alt: 1645;"> <col width="70" style="width: 53pt; mso-width-source: userset; mso-width-alt: 2560;"> <col width="108" style="width: 81pt; mso-width-source: userset; mso-width-alt: 3949;"> <tbody>[TR]

Thank you very much. I had other weekdays between the Fridays which caused decimals so I added a max if weekday = 6 and turned it into an array formula: =if(A2="","",max(if($G2:$G$200=1,$A$2:A200))-A2)/7+2). Row G has the IF weekday = 6 put 1.

Thank you again!
