Extend
Purpose
Allows a value in a non-repeating field to be used with every repetition in a repeating field.
Format
Extend(non-repeatingField)
Parameters
non-repeatingField - any non-repeating field (a field defined to contain only one value), or an
expression that returns a reference to one
Data type returned
text, number, date, time, timestamp, container
Originated in
FileMaker Pro 6.0 or earlier
Description
Use the Extend function with calculations involving both repeating and non-repeating fields.
Without the
Extend function, the value in non-repeatingField is used only with the first
repetition in the repeating field.
Examples
Extend(TaxRate) * Quantity * ItemPrice returns 1.197, .6606, and 1.497 when TaxRate
contains .06; the repeating field Quantity contains 1, 3, and 5; and the repeating field ItemPrice
contains 19.95, 3.67, and 4.99.
Item Count * Extend(if(Company Size > 100; Reduced Price; Price)) returns
$1250, $500, and $750 when
Reduced Price contains $50; the repeating field Item Count
contains 25, 10, and 15; and
Company Size is greater than 100. If Company Size is less than
100 and
Price contains $100, this calculation returns $2500, $1000, and $1500.
