I forgot to change/edit the email body and I moved on to the next step. I tried to go back but I'm not sure how I can go back to edit. I cannot seem to figure it out and now currently stuck. Do I have to delete everything and start over? If I do, how do you delete the template? When I try and click the down arrow to delete, it says the custom field is referenced somewhere else salesforce.
Sorry you're stuck but there's almost always a pretty easy fix! Don't try to start all over again–not necessary! Don't start undoing stuff and don't uninstall Max's Pitch Package, etc.
There's a 95% chance the same snag/fix is listed & answered in the Help FAQ. Check that first but if you can't find it there, post your problem + a screencap in the proper category below & we'll post a solution back ASAP!
