On Module Model-Driven App, number 15 video (Create Subgrids to Enhance Location & Service Area Forms), starting at 2 minutes and 40 seconds, it really gets hard to understand. It has frustrated me because Issue--1005 is mentioned as part of the tutorial video and I've followed all the tutorials concisely beforehand where there was no Issue-1005 part of the exercise for Location B03. Now I'm being instructed to consider Issue-1005 while learning subgrids. Also, I've been working with Building, Electrical, and Plumbing for Service Areas in previous tutorials, but now I'm seeing Carpentry and Cleaning added to the list of Service Areas in the tutorial for creating subgrids? Also, I'm unclear as to why I have no Issue Number for Location B02 and Location B04. However, for B01, it's Issue--1001, and for B03, it's Issue--1000. Did I miss something or misunderstand something? PLEASE inform me today if possible. Thank you.
