Tips
If you have some JavaScript code or other script code which is not working on your site, try adding it as a custom script.
Custom scripts can be added under Tools Add/Edit Custom Script
Paste the script or code into the field for "Custom Script"
Click "Add this Custom Script"
You will see MemberGate tag which looks like:
E.G
<cf_mggoogle adID=4>
Copy & paste that MemberGate Tag to the category or page where you want the code to display.
Adding it to the page as a custom script prevents the WYSIWYG editor from interpreting some of the Javascript as possible malicious code (and disabling it).
