Workspaces refuses to load any code

During Stage 5 of JavaScript Basics, I was trying to approach the challenge and offer a solution. My own solution wouldn't put anything up on the preview, even after asking prompts and document.write commands that should have processed. Even after directly copy and pasting the ultimate solution, the Workspace would preview nothing. No matter how many requests I made for prompts, returns, calling functions, nothing is going through. I've also found the Workspaces to be buggy like this in previous exercises, but only temporarily. What gives???
