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!
I don't see any of the three leads you were supposed to add in 3a. Were you able to get the screencaps in 3a working correctly? Which steps are you on now in 3b?
It looks like you haven't done Lab 3a at all yet. Lab 3b builds on things you create in Lab 3a. You have to do 3a first and then start 3b.
