Thank you Narayan, This is a Project report: The column I already have calculated is Project entry to a custom field called Requested Delivery Date: aggregator.function=AVG aggregator.valueexpression=WEEKDAYDIFF({entryDate},{DE:Requested Delivery Date}) aggregator.valueformat=val displayname=Entry to Completion textmode=true valueexpression=WEEKDAYDIFF({entryDate},{DE:Requested Delivery Date}) valueformat= Now, is it possible to get a day difference from this column to the Template duration? I hope that's more helpful. Thank you in advance! Ruby Aran
