Hello Victoria

Unfortunately, the Staff cannot provide support for the integration of custom codes so my support is going to be limited here

However, I will leave the topic open so that other users might eventually join in the discussion and help you out with this. Alternatively, I'd like to suggest seeking the help of a professional for help with integrating this code, which should be fairly easy considering the tools WebSite X5 gives you access to in order to integrate external codes

I remain available in case you have any other questions

Stefano
