Oh, wait, I see you're still on Lab 1b so you do need to delete them to keep your charts & graphs from looking weird. Sorry. Or you could start over with a fresh new SF account and just be sure you import the file only once this time. You wouldn't have to do Lab 1a. You could just start with Step 5 of Lab 1b. And if you email me, I could give you a promo code so you wouldn't have to pay again.
