I missed question 12 by .33 points, with the following message "Clustered Column Chart" on the sheet "Sheet1", the "Source" was not set as per the instruction.

Based on the instructions I selected cells A3:F7 and created a Clustered Column. I am only working on one sheet so this picture shows everything on the excel sheet.

Does anyone know what the message means by source??
