Hi Jayden!

You could try following line of code

```
<script src="../../Scripts/jquery-1.7.1.min.js" type="text/javascript"></script>
<script src="../../Scripts/jquery.maskedinput.js" type="text/javascript"></script>
<script type="text/javascript">
    jQuery(function ($) {
        $("#fax").mask("+1-"+"999-9999999");
    });
</script>@Html.TextBox("fax", null)
```

Note:\
"jquery-1.7.1.min.js" provided by MVC application\
"jquery.maskedinput.js" you can download from following link

[https://raw.github.com/digitalBush/jquery.maskedinput/1.3.1/dist/jquery.maskedinput.min.js](https://raw.github.com/digitalBush/jquery.maskedinput/1.3.1/dist/jquery.maskedinput.min.js)
