Hello,  
I have an input field for an e-mail address (string) on a website. This value also appears in alert, but in the payload it says null (see screenshot).

What should be the payload value in the script?

Thanks

Here is the script:

> ```
> submitHandler: function () {
> let emailvalue = document.getElementById("exampleInputEmail1").value;
> alert( "Form successful submitted! E-mail: " +emailvalue );
> 
> uibuilder.send( { 'topic': 'E-mail Adresse', 'payload': +emailvalue } )	  
> 
> }
> 
> ```

This is the result:

log in your browser's dev tools console the value to see whether you are indeed getting the correct element value  
if your selector doesnt find any element it returns null

```auto
let emailvalue = document.getElementById("exampleInputEmail1").value;
console.log(emailvalue)

```

```auto
uibuilder.send( { 'topic': 'E-mail Adresse', 'payload': +emailvalue } )	 

```

Tried it without the `+` ?
