Sorry, I would love to get this resolved. Are you using PieFed.zip? There also might be errors in the JavaScript console that will give a good hint to what the error is. If you’re not sure how to do that, you can search how to find JavaScript console in your browser or choice. Happy to work though the bugs here of over DMs.
Solving these types of bugs makes the app better for everyone. Please don’t hesitate to bug me with these types of errors.
