It wasn't previously a .zip file but I had compressed it during my troubleshooting. This is what the original file contained. The html file opens it in the browser and the folder "src" contains a JavaScript file called "Runtime". The file does work if you open it in the file itself.
There's your problem. It's supposed to be a .zip like that, but the file called "Stickman Standoff.html" should be called "index.html" instead. Only needs to be that way in the .zip file you upload.
