Hello, it seems like the typewritter addon is not available in the page, to add that you can do this:
Add the CSS:
<link rel="stylesheet" href="vendor/rs-plugin/revolution-addons/typewriter/css/typewriter.css" /></script>
Add the JS between tools and the main file:
<script src="vendor/rs-plugin/js/jquery.themepunch.tools.min.js"></script>
<script src="vendor/rs-plugin/revolution-addons/typewriter/js/revolution.addon.typewriter.min.js"></script>
<script src="vendor/rs-plugin/js/jquery.themepunch.revolution.min.js"></script>
Please try that and let me know if you need further assistance.
Kind Regards,
Jonas
