So I followed along and have become stuck haha.
So I was able to download the HTML file of my landing page which I opened in Sublime Text to add the MV Lab Code and saved it as .PHP.
I then uploaded it to my server which was also successful but when I entered my URL in the browser it wasn't working.
I will reach out to
CPV Lab support and see if I can get to the bottom of this and report back some results.
