*A general interviewing data field is a storage location for information. While most questions types like numeric, select radio button, select combo box, and open-ends only take one storage location, some question types, like grid questions, ranking, or other-specify questions contain multiple data fields. Looping over portions of your survey can also increase the number of required data fields. More information about data field calculations may be found here: How License Sizes Are Counted.
