Gary Czychi, GC Consulting

Given a field value, returns its current Record Number within the current Found Set

Sample Input:
GetRecordNumber ( author::name ; "Douglas Adams" )
Sample Output:

 Then copy & paste into FileMaker Advanced's Edit Custom Function window.

Returns the first line number that contains _value, of a list of _field values of all records in the current found set
Returns NULL ("") when _value is not in the list
Returns the correct line number , no matter whether the found set is sorted or not !
=> which is IDEAL for Go To Record/Request/… script step

If it doesn't work, you probably not calling it with a field reference, but with a field value:
_field is a field reference, not a value:
If the field name is stored inside a field, use Evaluate ( ) => GetRecordNumber ( Evaluate ( g::tmpT ) ; g::tmpN )

Based on the ListValues ( Field ) recursive function from Koji Takeuchi:
Given the list of Koji Takeuchi, added number strings at the beginning of each line, followed by a tab character and the line value
At the end, searches for a tab, the _value and reads its line number, then returns the line number

GetRecordNumber ( author::name ; "Douglas Adams" )
=> Returns the number 42 (if the record with "Douglas Adams" is the 42nd record in the current found set).

This is my Custom Function and I want to edit it


Undefined Null is used in this function.
I tried replacing it with "", but not get result.

sorry about the «Null» function, you're right. I already changed it to "", which is the exact same thing, as you have done. I use the Null function because it makes for much better reading and understanding of code afterwards.

If it still doesn't work, you are probably not calling the function with a field reference, but with a field value (whereas the _value is a value):
_field is a field reference (not a value):
If the field name, for example «author::name» is stored inside of a field, use Evaluate ( ) => GetRecordNumber ( Evaluate ( g::tmpT ) ; g::tmpN )

This will probably do it.

Thanks for your question. Now, it should be clearer.
