Copy (or move) your three sound files, Hitman.mp3, roblox.mp3 and Fortnite Floss for 6 minutes.mp3 from your Downloads folder to the sounds folder in your test scenario folder. Then drop the paths of all references to those files (just use the filenames with their suffixes). It should run on this site after uploading with those changes made. I do not know if the spaces in the last filename are allowed, however (you might try renaming that one).
