In situations where you are unsure what is going on, it always helps to fake the data.

As i dont have your Emails - i am faking the data here...

A single line string will NEVER equal multi-line string

What do you expect to happen?

Are you looking for msg.payload.x inside? on one line? in a loop?

Please explain your logic

i know that one single line string isn't equal multi-line string, i want to know if it's possible to look inside the file .log and see if the input msg.payload.x(10987654321) is inside. then if it's inside "RIGHT" else "WRONG".

But you didnt say that.

You said

> [@belo0196](#):
>

Also, your terminology is incorrect, node-red doesnt "look inside" a file - you load the file and scan its content.

you could use the JS string [includes](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/includes) function

```auto
if(msg.payload.y.includes(msg.payload.x)){
//found it
} else {
//not found
}

```

NOTE: If you are want to be proficient in node-red then you really should do some JavaScript training Nothing too heavy - something online - or YouTube JavaScript for beginners.

I don't see the reasoning behind a manual comparison function when a switch node does the same thing.

Your question doesn't make a lot of sense. do you want to turn off the opposite pin?

If so, then instead of `return [msg,null]`, `return [msg,{payload:false}]`

That will send a false value to the 2nd output of the function to turn off the opposite pin.

Do the reverse for the 2nd `return`
