Page Animation | Nav Bar Light Doesn't Work

Hi, I am copy pasting an existing Navbar from another website I made
onto my new website. Despite my best efforts, I can’t get the Page Interaction to work where it shifts in light mode for both desktop and mobile.

Nothing happens, although the same navbar works on the previous website. I simply want the navbar to have no background and when I scroll it needs to give itself a white background and inverse my text colours to white to black.
