repeating fields.

standard deviation of a population in the first repetition fields, then the standard deviation
of a population in the second repetition fields, and so on.

Description
Returns the total of all valid, non-blank values in:
a repeating field (repeatingField).
a field in matching related records specified by (table::field), whether or not
these records appear in a portal.
several non-repeating fields in a record
(field1;field2;field3...).
corresponding repetitions of repeating fields in a record
(repeatingField1;repeatingField2;repeatingField3), if the result is
returned in a repeating field with at least the same number of repeats.
several fields in the first matching record specified by
(table::field1;table::field2;...). You can include fields from different
tables
(table 1::field A;table 2::field B...).
Examples
An Invoice table has a portal showing line items.
Sum(LineItems::ExtendedPrice) totals the amounts for all items on the invoice.
A TimeBilling table has a portal showing time worked on a project. Hours is a time field.
Sum(Hours::BillableHours) returns the total number of billable hours on a project.
Thus, if the portal shows 40 hours and 15:30 hours, the total billable hours are 55:30, or
55 1/2 hours.
