Sum Values from Select Rows
Compute the total delivery charges recorded within a reporting period:
([DateDone] >= [_THISROW].[BeginDate]),
([DateDone] < [_THISROW].[EndDate])
SELECT(Deliveries[DeliveryCharge], ...)gets a list of delivery charges from select rows in the Deliveries table.
AND(..., ...)limits the SELECT() results to only those rows that match all of the conditions.
([DateDone] >= [_THISROW].[BeginDate])limits the count to only rows with a DateDone no earlier than the report's BeginDate.
([DateDone] < [_THISROW].[EndDate])further limits the rows to those with dates before the report's end date.
SUM(...)totals the values from the result of the SELECT().
SUM(1, 2, 3) : the arguments are not in list form. To fix, wrap them in LIST() to construct a list:
SUM(LIST(1, 2, 3)).
SUM( some-list )
some-list (list of any numeric type)
AppSheet must be given enough context to determine what type of values some-list contains, that its contents are or will be numeric. To that end, some-list must be one of the following: a column value of type List that contains numeric values; a column list (e.g., Products[Price]) for a column of a numeric type; or a constructed list (e.g., with LIST()) of a numeric type.
The computed sum of the values in some-list.
