//["Alain Martin","Jane Doe","John Smith","John Doe"]
//["Lyon France","Eching Germany","Paris France","Berlin Germany"]

must be someting like that

//$name=["Alain Martin","Jane Doe","John Smith","John Doe"]
//$address=["Lyon France","Eching Germany","Paris France","Berlin Germany"]

but not really, $address contains object, not string? maybe exemple not correct

I launch it and have some errors "compare function doesn't provide consistent results"

ok it's fixed thanks! Correct code is $name.multiSort(Formula($1.value.firstname<$1.value2.firstname); [$address])
