When I originally submitted this lab, I realized I didn't include the enthusiasm, so I'm redoing the lab. However, I can't get past step 19/20 because when I click on New, it doesn't have a section for comments.

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
Sure, np, Amanda. Let me know if you hit any other snags.
Hope you enjoy the labs and will feel like you've learned a lot. If so, please let your instructor know. Thanks! :)
Thank you very much for all your help!
You need to make sure you do every step and do them in the order they are given, ok? But just start at Step 91 and go from there.
Ok, so I have gone into your account and undeleted that Pitch record and I added Enthusiasm for you and everything is ready for you now to start at Step 91 and continue to the end and you will get the correct final display for ScreenCap #3, ok?
Do not go back to Step 19 or any other step. Just go straight to Step 91. Begin now with Step 91 and then continue with 92 and 93 and so on, ok, until the end.
I had done the entire lab but when I took the last screenshot, I realized I didn't see any of the enthusiasms, which is when I decided to stop and start over.
But you weren't even supposed to create Enthusiasm until Step 79 so you must have gone past Step 20 before and past ScreenCap #2 at Step 51 already and way beyond that if you then realized you forgot to add Enthusiasm. Didn't you get the screencap at 51? What step were you on when you decided to stop and start over again?
Have you done the 3 steps? I need to know your name so I can access your account. There are lots of Amandas.
The only one I have completed is step 17 since I was not able to get past step 19
Ok, why don't we try this. There are 3 deliverables for Lab 2a. Step 17, Step 51 and Step 113. Do you have any of these completed properly and if so, which one(s) do you still need?
Then, do the following three steps so I can access your account and try to fix everything:
1) Click on the character at the upper right corner and then, in the popup, click “Settings” 2) On the left vertical menu, click on “Grant Account Login Access”
3) On the row for The Max Labs Project, use the menu to change “—No Access—“ to “1-Month…”
Yes I understand that, but what I'm saying is that I had already deleted pitches and gone back prior to coming onto the help forum, so I'm not sure what to do past step 19. The last screencap is not what I need anymore, as I unfortunately went back before and attempted to solve it myself by deleting things, which I'm now seeing was not the right choice
What I'm saying is you don't need to go back and redo everything. You can't. It won't work. You deleted Comments from Pitch as you were doing the lab which was correct. You would have to undo everything first and then redo it. It would be insanely hard to do. And you don't need to. Just do what I said to add Enthusiasm and go from 79 thru 86 and then 112 and 113 and get your screen cap. Isn't that last screencap all you need at this point?
Originally I just needed to add enthusiasm, but I attempted to redo everything because I thought it would solve the issue. However, now I am not able to get past steps 19/20 because the comments section does not appear when I try to make a new pitch.
Ok, so it sounds like you're saying you want to just add Enthusiasm to the Meeting object so it shows up properly in the last screen capture at the end, right?
You don't need to go back and redo everything (and you're right, that would be complicated and won't even work bc of the changes you've made to everything by this point). But all you need to do is to go to Setup > Object Manager > Meeting and then click Fields & Relationships and New. Then you can add Enthusiasm to Meeting according to Step 79 that you skipped before.
Then redo Steps 80-86 but only for Enthusiasm. Step 84 tells you how to move Enthusiasm to the right place in the list.
Then go to App Launcher > Marketing > Pitches tab and click on the Spray & Pray Pitch record and open each of its 3 Meeting records and add the Enthusiasm values shown in Step 99, 105 and 110.
Then you should be able to do Steps 112 and 113 and see the correct display for screen-capping!
