And the meeting ID was not start at Mtg-01 to Mtg-13. I tried several times to figure out but don't know where to change. Please help~

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!
Oh, wow. Yeah, it looks like you must have repeated the importing steps a bunch of times for some reason. And you must have deleted a bunch of the extras but not all of them. Unfortunately, computers are very picky so you really have to stick to the exact instructions.
At this point, I think you may want to abandon your current account and get a brand new fresh one and then catch up quickly to where you were. I can help you do that and give you a promo code so you don't have to pay again. Basically, you can skip Lab 1a and then you have to do about 1/3 of Lab 1b and about 1/2 of Lab 2a, and then you can start 2b. Just email me at tim.hill@themaxlabsproject.com for details and your promo code.
Thank you for replying! Or is there any other convenient ways to solve this problem if I don't start a new account? Could you please get access to my account and see where I should deleted the data? My Salesforce.com Organization ID is 00D5Y000001bIyt.
@Mengting Dai Well, it is so messed up at this point it would take hours to try to reconstruct the missing data and also delete each of the extra records one at a time. It's really not worth trying to fix it at this point. Much easier/faster to start over with a new account.
It should only take about 45 minutes to catch up to where you were already. But you have to carefully do each instruction correctly. You can't skip over them and you can't do extra things. Just exactly what the instructions say and then you will have no problems.
@Dr. Tim, Max Labs Director Got it. I already sent a e-mail to you.
@Dr. Tim, Max Labs Director I have this same issue I realized that a lot of the information was duplicated by the time I had already tried to redo it several times unfortunately. I had imported the information several times because the first time the cell for mobile was not coming up but once I had resolved it it was too late.
