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.
Before you post make sure you check the Help FAQ for an instant solution first. Then, if you can't find it there, you can post your problem here and we'll get to it ASAP (within 24 hours), but be sure you:
post in the right category
INCLUDE AT LEAST ONE SCREENCAP IN YOUR POST TO SHOW THE PROBLEM!!!!!!!!
explain the problem clearly
I click clone, and it shows a page, I can not find the Template Unique Name, and after that, I save it and I can not find an edit.( this picture is after I clicked the clone, I am very sure I clicked clone because I tried too many times, I know clicking edit will show the same page, but I do not know why)
That is the wrong page because you didn't apply the browser settings given at the top of the Lab 1a cover sheet. You have to use those settings and allow 3rd party cookies/tracking, depending on your browser. Look where it says "Salesforce may not work correctly if you don't use these settings..." Make the settings and then it will work.
