Hi everyone,

i am trying to get the last 3 positions of the payload of this message

31/8/2020 16:37:23[node: SWITCH 5](http://localhost:1880/#)test : msg.payload : string[25]

""DB0020\_AUTO".PRUEBA5,101"

I need 101 value, but i dont want a split after "," because in this way i would get 2 messages and i dont kwow how to differenciate between the variable name ("DB0020\_AUTO".PRUEBA5) and the value 101

in other way i wrote a function in order to get the last positions of the array but doesnt work

message = msg.payload  
A =   
A[0] = message[25]  
A[1] = message[24]  
A[2] = message[23]

msg=A;

return msg;

thank you for any clue in any way

In a function node you could use:

```auto
m = msg.payload.split(",")
msg.value = parseInt(m[1])

return msg

```

Output

@bakman2 No offence but I really think you should use a keyword to declare the variables in your examples, just to not teach bad practices to people new to JS. It's not Python even if Node-RED doesn't use a strict interpreter 🙂.

Or if you want the answer in the payload then

```auto
msg.payload = parseInt(msg.payload.split(",")[1])
return msg

```

If you want the answer left as a string then

```auto
msg.payload = msg.payload.split(",")[1]
return msg

```

No offence taken, it is a keyword: short for message 😉
