I created a new spreadsheet, copied the top two header rows from the sample data import for v1.4, then put my data in. As soon as it begins, it errors with "line skipped - Error Object reference not set to an instance of an object.", then I stop it after 100 rows. At the end of the 100 errors, it says
Error while adding base versions:Invalid column name 'V_Tax2'.
Invalid column name 'V_TaxExtra'.
What am I doing wrong here? I've done the data import before. This time something is off.
