Question: I am working with C# and i am loading a jquery file 1.8.1 in the layout, but there is a module pulling through which is adding another jquery file 1.6.1 is there any way for me to remove it without physically going in and remove it so i need to remove it dynamically. 

Thanks.

Answer: 
You assigned the id to the div tag, but you need to assign the id to the img tag. Then you should get the reference to the image and can then change its src:

`<div class="image_cell">
 <img src ="StarOff.gif" id="1"/>
 </div>`
I noticed that `correct_answer` is a Number so I converted it to a String (using `toString`) so it can be used to match the `.image_cell` `id`. I added an `input` to demonstrate it actually functions.

See Snippet 

```js
var correct_answer = 0;

function starOn(correct_answer) {
  var x = correct_answer.toString();
  var iCell = document.getElementById(x);
  var iStar = iCell.querySelector('img');
  iStar.src = "http://findicons.com/files/icons/249/xmas_pack/48/star.png";
}
```

```css
.image_cell {
  display: inline-block;
}
input {
  width: 48px;
  text-align: center;
}
```

```html
<div class="image_line">
  <div class="image_cell" id="1">
    <img src="https://cdn0.iconfinder.com/data/icons/super-mono-basic/yellow/star_basic_yellow.png" />
  </div>
  <div class="image_cell" id="2">
    <img src="https://cdn0.iconfinder.com/data/icons/super-mono-basic/yellow/star_basic_yellow.png" />
  </div>
  <div class="image_cell" id="3">
    <img src="https://cdn0.iconfinder.com/data/icons/super-mono-basic/yellow/star_basic_yellow.png" />
  </div>
  <div class="image_cell" id="4">
    <img src="https://cdn0.iconfinder.com/data/icons/super-mono-basic/yellow/star_basic_yellow.png" />
  </div>
  <div class="image_cell" id="5">
    <img src="https://cdn0.iconfinder.com/data/icons/super-mono-basic/yellow/star_basic_yellow.png" />
  </div>

</div>
<br/>
<label>Type in a number 1 to 5</label>
<input oninput="starOn(this.value);">
```
