Hi. another deveop is asking i add the following code <script src="https://allcheckedtools.co.uk/showcase/showcase.jQuery.js";></script>

Your site must be using jQuery, After you've included jQuery (usually towards the end of the page) paste this line of code:
<script src="https://allcheckedtools.co.uk/showcase/showcase.js";></script>

If you are using Wordpress or joomla you may need to use this line instead:

<script src="https://allcheckedtools.co.uk/showcase/showcase.jQuery.js";></script>


any ideas please thanks
