Hello, I was hoping for some help with the slideshow gallery at this link: https://www.w3schools.com/howto/howto_js_slideshow_gallery.asp I was trying to add a slideshow to a website I am creating. However, when I add the exact same code into my own, the slideshow does not show up at load time. I wasn't sure why this might be? I made it a separate file and it loaded perfectly but when I added it to my code it did not. I assume there is an issue with something else I have already written for a different part of the website but I was not sure what would be causing the problem. The slideshow works if I click on one of the thumbnails. But I need it to show up at load time.
