Hi All,

Complete newbie to node red, so please excuse my basic question.

I have a variable I’m converting to a message.

If 0 == message 1  
If \< 20 message 2  
If \> 20 message 3

The problem I have is I don’t want to include 0 for message 2.  
So message 2 need to be less than 20 but not = 0 or less than 20 but greater than 0?

Thanks in advance.

```auto
if (x == 0) {
   do something i.e. message1
} else if ( (x > 0) && (x < 20) ) {
   do something i.e. message2
} else { // at this point x has to be 20 or more.
   do something i.e. message3
}  

```
