It looks like what's happening with your page is that you're using the script loader from the Effects Maker but mixing that with the code used with the actual script! It should work if you replace "kallistero_script_loader.js" with "wireframe_gridlines.js"
Added a "scanlines mode" button to NaviA. I was just going to have this scanlines effect for my next new page, but I thought it'd be fun to be able to put scanlines on ANY page, so I added a pure-CSS version of it to NaviA!

i figured it out, had to set the page as a div element for the background to work
