HOW DO I ADD A FORM TO MY WEBSITE

I have generated a source code

<script type="text/javascript" src="//form.jotformeu.com/jsform/51245870240348"></script>

This is my URL

http://www.rotary-site.org/index.php?SiteID=389&lang=en

I'm not sure where to paste the source code. Would appreciate your help. 

Paste the code into your web page where you would like to display it. Usually somewhere in the body section of your webpage and within tags.

If you are using a web-builder, let us know which one is if this is the case, there should be an HTML area where to paste the code.
