Put your formula in the "value". That way each time you add a row you'll have a new calculation showing the mileage.https://www.infopathdev.com:443/forums/thread/96543.aspxThu, 20 Mar 2014 14:21:24 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:96543ashleyfoozi0https://www.infopathdev.com:443/forums/thread/96543.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=96543Hi. I have a monthly form for our service guys to enter their fuel purchases and mileage in a repeating table. The problem is the mileage.In theory to calculate mileage you subtract the last entry's mileage from the previous months closing mileage (the current month's opening mileage). I have a text box outside the repeating table for the opening mileage. How do I subtract the last entry in the repeating table from the opening mileage?
