I'm expanding my work so far from a single entry on a repeating table to a more standard table layout. Each row contains data for one day so I know I can get the difference between two entries and shift it to decimal number in ActualTime and then work the rule magic to get totals. But I need to now expand this to cover up to 4 in/out entries per row. I attached the following but am struggling to get the xpath to calc all of these together.
