Field can be any of the following:
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...).
The Accounts layout has a portal showing installment payments made.
Count(Payments::Payment) returns the number of payments made on an account.
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 6.
Count(Field2) returns 4 when the calculation isn’t a repeating field.
Count(Field1;Field2;Field3) returns 3, 2, 1, 1 when the calculation is a repeating field.
Note  When a referenced field is a repeating field, the Count function returns the total number of valid, non-blank values in the first repetition field, then the number of valid, non-blank values in the second repetition field, and so on.
