dhtmlxCalendar minimum install and config

I am creating a form and using the calender. I have downloaded the files and set up the some of the files on the server - see the attached list.png. On the form I have set up and the calendar so it works and is linked via an icon and input field. However what is not working correctly is the calendar shows up as a list - again see the attached list.png. In the head section of the html I have placed the lines below corresponding to the file locations:

<link type="text/css" href="../dhtmlxcalendar/dhtmlxcalendar.css">
<link type="text/css" href="../dhtmlxcalendar/skins/dhtmlxcalendar_dhx_skyblue.css">
<script src="../dhtmlxcalendar/dhtmlxcalendar.js"></script>

The whole calendar is there and it works just fine other than how it displays. Can someone explain why the calendar is showing up as a list and not a properly formatted calendar? What is the bare minimum file configuration and setup for the calendar to work properly?

Incorrect image path or calendar skin. Please, look in the development tools
Or attach completed demo to inspect it, if everything is correct
