Your function node is sending a message that has the following structure:

msg = {
       payload: {payload:"Your String"}
      }

In this way, your message payload is equal to the following Object:

 {
   payload:"Your String"
 }

To return directly the string, you have to replace

node.send({payload:out}

with

node.send(out)

Good Afternoon
I just wanted to thank you for you help not only did it work instantaneously but it has saved be stopping up for a third night, I really do struggle with the whole payload message part of node red, your explanation was very intuitive.

Again thank you :grinning:
