Description	It is used for setting the length of each question type in some data export formats.
Business logic	When the export position value is specified, the export length will be generated automatically when the user skips the Export position field. This length is generated based on the question type. If its export length value doesn't satisfy one of these condition above, the error message is "The export length of this question is invalid. Please type the valid value for this property."
Formatting	For each question type, the length must be larger than or equal to the value below: - Single question type: the length of the answer option with the highest value - Multi question type: the length of the answer option with the highest value - Scale: the length of the maximum value - Number: larger than 0 - Text: larger than 0 - Open: larger than 0 - Single-Grid: the length of the answer option with the highest value multiplied by the number of sub questions. - Multi-Grid: the length of the answer option with the highest value multiplied by the number of sub questions. - Scale-Grid: the length of the maximum value used in the sub questions multiplied by the number of sub questions. - Text-Grid: 50 larger than 0 - Multimedia: larger than 0
