I want two input fields to be subtracted from each other and then stored in a global token.

this must be in a dan card.

What have you tried? What isn’t working? What don’t you understand? Where is your code?

You have been posting variations of the same question for days now.

</div>

```auto
module.exports = async (options) => {

  const { app, args } = options;

  const w = Number(args.number_1);

  const x = Number(args.number_2);

  const y = (args.Answer);

  const y = await this.homey.flow.createToken(`${y}`, {

   

    type: "number",

    title: `${y}`,

  });

  const z = (w + x);

  const result = (z === y);

  app.log(`The sum of ( ${w} + ${x} ) = ( ${z} = ${result} )`);

  await myToken.setValue(result);

}

```

this is the basic version, this is to test and then work out further, but the basics don’t work yet.

You can’t declare a const twice (`y`) to begin with. But your `app.json` is invalid, hence the errors.

How should I solve that no new token is created but user can determine a token themselves.

See code above.

Have you fixed the error of defining the const z variable twice?  
If you post sample code make sure it is free of such simple errors or we don’t know if that is simply the cause.

the problem is i want the user to be free to choose any variable(token) created in the homey flow interface and not a new one how do i do this ?

twice the same variable is not ok, I know that too, but how do you solve this problem?

Either give one of them a different name or define it with let instead of const.

I’m pretty sure you can’t, at least not using the SDK (perhaps with the Web API but doubt it). Tokens (also global tokens) are tied to a specific app, and only that app can change their value.
