SUM(Classes[Seat Count]) : The sum of all values in the Seat Count column of the Classes table. Equivalent to SUM(SELECT(Classes[Seat Count], TRUE)). See also SELECT()

SUM([Discounts]) : The sum of the items in the Discounts column value, where Discounts is of type List or EnumList.

SUM(LIST(1, 2, 3)) returns Number: 6

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().

Common Problems

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.

Return Value

The computed sum of the values in some-list.
