HI @gwilkinson31 ! For this issue you would need to make a separate GI which would group and SUM these amounts as there is no way to use resulting widget data to make another widget, at least currently.
As long as they are based on the same data then they should be consistent, but it could require making a separate GI if the GI used for the original pivot isn’t already grouped.
The SUM() function or SUM Aggregate Function can only operate when a grouping is applied to the GI, but it might be quick if you can simply copy the GI and apply the necessary grouping, then make the widgets based off the needed summed fields.
