My simulation is not working. Every time I try to delete the Pitches tab in step 3, this screen pops up which messes with the rest of the assignment:

Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, uninstall Max's Pitch Package, etc. That can make it worse. There's a 95% chance the same snag/fix is listed & answered in the Help FAQ. But if you can't find it there, post your problem here.
Make sure you post in the right category below & be sure to include a screencap showing the issue!
You have already installed MaxzPitchPackage which contains the new Pitch object that should not be deleted. If you have two Pitch objects you should delete the one you made in Lab 1a, not the one giving you that message. In the Object Manager, the old one will say Pitch__c next to it. Delete that one. If its already gone then you already deleted it or never created it so go on with the steps after the installation completes. No need to delete. If you didn’t do 1a then you didn’t create a Pitch object and the cover sheet told you to start with Step. 5. You have to do all the steps exactly and in order given.
