FLOW Error: When Importing CSV Data FLOW Says "Correct before import"
Generally FLOW will display this error if there are two or more columns with the same title in the CSV (e.g. two columns labeled "Teacher")
Open the CSV you're trying to import
Double-check the headings to make sure there aren't any duplicate names.
Also double-check that all subjects' first and last names have information in the cells.
FLOW will not import empty first and last name fields from a CSV.
