PHP Getting a value from a Multi Layered JSON Array - php

Question

I seem to be having some trouble with JSON arrays. I was wondering if someone could please assist me.
I have the following JSON Array, and I want to get the figure in invoice_number
$json = '

}';
The code I was trying to use is but it comes up with error Undefined property: stdClass::$invoice_number
$decoded = json_decode($json);
echo $Info = $decoded->transactions[0]->payee->invoice_number;
Could someone please tell me why this does not work?
Thanks
Robert
