Look at the URL you are calling the JS file with. You are not calling it correctly. If the file is in a folder titled “js”, than the file path needs to match that.
Right now, this is the file path you are using: http://eternalvale.infinityfreeapp.com/dnd/dmscreen/quickref.js. As you can see, the “js” folder does not exist in that path. You need to update your code to call the correct file, and make it valid HTML, or you may run into more issues later.
