Sum of a filtered slice column

[smac]

Hey All, I am pretty new to AppSheet so any help is really appreciated.  I would like to display a sum of a filtered slice column to show total hours work.  Here is a screen shot of what my display looks like.  I would like a sum of the current week as well as previous week.  Thanks!

You can try putting an expression similar to below in the Display name  of each view supposing you have two slices (this week and previous week)

"Current Week, Total Work Hours = " & SUM(Current Week Slice[Total Hours])
