Lab 2b

I was working on my Lab 2b and for my first checkpoint it was showing that there was an error in my meeting pitches. It is telling me to redo everything from lab 1b, I was wondering if there is any other way to fix this error so I could complete lab 2b. I know where my mistake was and it was in lab 2a when I was inputting the Mtg{001}. I don't think I cloned it right because it gave me different numbers that weren't needed for lab 2b, but they included the same information.
