A double quotation mark, which defines where one filed starts and another field ends, is missing. Please add the missing double quotation mark and reupload the record.
This error occurs when your file does not contain an expected double quotation mark. In a tab-delimited text file, quotation marks are used to enclose data that includes one or more special characters. If a field of data includes a double quotation mark (such as when using it to represent inches), that field must also have a double quotation mark at both the beginning and end.
If you create your tab-delimited text file from a Microsoft Excel template, Excel should automatically include the proper number of double quotation marks.
