I was around through a problem in step 84, and tried to restart what I had done by going backwards. I deleted the tabs, and tried to delete the updates in Julia and so on. Eventually I tried to start all over by deleting the work I had done, and even tried to upload the same set of data, to try to make the meetings tab. When trying to make the meetings tab, I ran to the problem of not having to option to add (contact name, email, mobile, enthusiasm and comments) over to the Selected Field.
Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, eg. uninstall Max's Pitch Package, etc. That can make things worse.
