Hi Nicha! I confirmed that I have tried to join and look into this for few times, it seems like the column of “2015_Total_malaria” has not been displayed based on original file as well as I submitted the completed assignment 2.3 without having “2015_Total_malaria” column in the report. Hopefully, Ajarns may provide further information/clarifications for this issue that whould be really appreciated.
Thank you in advance krub. 😊
