So - on your working hours field, you could add rules to set the total and OT based on the date. I'll modify your sample here shortly & attach.https://www.infopathdev.com:443/forums/thread/124848.aspxTue, 12 Apr 2022 10:10:01 GMT033a2e2d-04e2-4a9d-be01-a4634161eefd:124848hainh19840https://www.infopathdev.com:443/forums/thread/124848.aspxhttps://www.infopathdev.com:443/forums/commentrss.aspx?SectionID=41&PostID=124848Dear Support team, Could you please help me this issue: - I have timesheet form with Timein & Timeout - Working day is from Monday - Saturday, Sunday is off.
