I am trying to fill a large ss column with the same formula, when i do a fill down it adjusts the cell number - so for example - I am putting in =WORKDAY($[Due Date]88, -85) - I want all the next 30 rows to have that same formula but when i fill down the "88" changes to 89, 90, 91 etc. The only other way i have found is to cut and paste - any ideas?
