I am trying to correct my check points for lab 3a and it says that "Can't find a Classic Email Template named "alert Riley about a new Bay Area lead" (Steps 30-52) or anything close to that. You need that template to do most of the rest of the lab (thru Checkpoint 3). If you want to fix this and re-grade, click here to see how.", but I already have the files so I can't make another one and they won't let me delete either. It seems like this step is completed and I can't fix the other points without clearing this one first.

Yeah, so on your screencap I can see you put the underscores between the words in the Email Template Name. They only belong in the Template Unique Name where you can't have spaces. Just go in and edit the template and take replace the underscores with spaces but ONLY in the Email Template Name slot. Leave them in the Unique Name slot.
Then regrade and it should be good.
