Hi!

I’ve created a checkbox using `box1 = createCheckbox('test', true);` and I want to be able to change the state of that checkbox. However, `box1.elt.checked` returns `undefined`. This seems to be, because `box1.elt` returns the checkbox wrapped in a div.

```auto
<DIV>
 <INPUT type="checkbox" id="jxl7300rqxa"></INPUT>
 <LABEL for="jxl7300rqxa">test</LABEL>
</DIV>

```

How can I access the input div and be able to change the `.checked` state?

Can’t you just call method **checked()** over variable _box1_?

- [reference | p5.js](http://p5js.org/reference/#/p5/createCheckbox)

```auto
box1 = createCheckbox('test', true);
box1.checked(true);
print(box1.checked());

```

Oh, that worked. Thought I tried that multiple times before, but guess I didn’t.

Thank you.
