Function definition: (Copy & paste into FileMaker's Edit Custom Function window)

/*
CF Guillotin ( Victim )
nimmt das erste Element des Opfers weg
Beispiel: Guillotin ( "Head¶Chest¶Legs" ) = "Chest¶Legs¶"
*/

Let (
	glieder = ValueCount ( Victim ) - 1
	;
	If ( glieder > 0 ; RightValues ( Victim ; glieder ) ; // es ist noch etwas da
                                 "" )// sonst halt nichts mehr
	     
    )

Whenever you have a list of values in a variable and need to go through them in a loop, you can always use getvalue ( $list ; 1 ) and use the Guillotin function afterwards to shorten the list. Don't forget to exit the loop if ( isempty ( $list ) ).

The result of Guillotin ( "Chest¶Legs" ) is "Legs¶" rather than "Legs". However, the valuecount function returns 1 in both cases.

If you use Guillotin ( "Legs¶" ) in the next round, the result will be empty and you can safely test the state using The isempty function.

The result is not as documented. RightValues () will append a Â¶. Guillotin ( "HeadÂ¶ChestÂ¶Legs" ) = "ChestÂ¶LegsÂ¶"
