Material 3 design kit isn't working

So I pasted some components frommaterial design on a page. I edited some of it and left some but when I present it, the page is blank and only the horizontal line I added myself shows. What am I doing wrong please? Thanks in advance

Ohh. It is even blank here too. I will add a screenshot then

I figured it out
