Examples
A portal displays the related values 5, 6, 7, and 8 in the field Scores.
StDevP(table::Scores) returns 1.11803398....
In the following examples:
• Field1 contains two repetitions with values of 1 and 2.
• Field2 contains four repetitions with values of 5, 6, 7, and 8.
• Field3 contains four repetitions with values of 6, 0, 4, and 4.
• Field4 contains one repetition with a value of 3.
StDevP(Field4) results in an error because the population standard deviation of a
single number is not defined.
StDevP(Field2) returns 1.11803398... for a non-repeating field.
StDevP(Field1;Field2;Field3) returns 2.16024689..., 2.49443825..., 1.5, 2 for
repeating fields.
When a referenced field is a repeating field, the StDevP function returns the
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.
Sum

Sum(field{;field...})
Parameter
field - any related field, repeating field, or set of non-repeating fields; or an expression
that returns a field, repeating field, or set of non-repeating fields.
Parameters in curly braces { } are optional.
Data type returned
number
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...).
