Lab 1b step 140
I keep getting the error "The column Expected Value was supposed to be added to report "Total Expected Value of Pitches So Far" (Steps 140). If you want to fix this and re-grade." I fixed the error, but I'm still getting the error and have gotten points off. I have tried to fix it again and resubmit as well.

Try deleting that report and remaking it, following the steps carefully.
