Using Repeats in XLSForm with Google Drive and Aggregate

Support
3

Google Drive has a few limitations.

  1. No repeats (see Repeat groups and google sheets upload - #11 by LN)
  2. The form must have less than 254 variables. Any non-group row (e.g., text, integer, select_one, geopoint, calculate, date) is considered a variable.
  3. Only alphanumeric characters (123ABCdef) and dashes (-) are allows in the name column of the survey and choices sheets.
