Question: I have an `.each()` function that measures the width of each of the images within the class of `.item`. I need all the widths to be measured and then added to a variable. The variable then needs to be passed out of the function. This function below is only half done, I just dont know how to finish it off.

Any help much appreciated.

```
$('.item img').each(function () {

    var i = $(this).width();

});

$('.overview').css('width', i);

```

Answer: 
```
var i = 0;

$('.item img').each(function () {

    i = i + $(this).width();

});

$('.overview').css('width', i);

```
You were iterating through the items but the width is over written instead of adding up.

```
var i = $(this).width();

```

this would be 

```
var i += $(this).width();

```

Also define I outside function to retain its value between function calls. The variable name i is not very appropriate here it could be something like totalImagesWidth

Try this

```
var i = 0;
$('.item img').each(function () {

    i += $(this).width();

});

$('.overview').css('width', i);

// you can pass this to some other function as well
somefunction(i);

```
