i'm stuck trying to convert feet to miles. here is my code so far:

```js
function convertData() {
  var distance = document.getElementById('distance').innerHTML;
  var mile     = 5280;
  var result   = distance /mile;
  document.getElementById('distance').innerHTML = result;
};

```

and from the answer here, i'm trying to implement this to the

document.getElementById tag up in the beginning of the document found here..

```html
<input type="button" value='Convert to Miles' onclick="convertData();">

<input id="distance" type="number" value=453454>

```

..so when a user clicks that button, the data gets converted.
this is the default line when a user opens a page on first try:

any advice or thoughts?
