Sync & Save expands Select One and Select Multiple fields to provide maximum flexibility in handling user input.

• Select One and Select Multiple fields first appear in the list of form fields and return the underlying value selected by the user:
  
  
  
  If more than one value was selected in a Select Multiple control, then the chosen values are divided by a single space.
  
  
  
• The same Select One field will appear again further down the list of fields, but this time with all the possible options broken out:
  
  
  
  In this case, the field has underlying value options of "option_1", "option_2", etc.
  
  Each option is presented in two ways: _Selected contains 1 if the option was selected and 0 if the option was not selected. _Text contains the text visible to the user (not the underlying value) if the option was selected and nothing if the option was not selected.
  
  The final _Text field contains the text selected by the user (not the underlying value).
  
  
  
• The Select Multiple field will also appear again further down the list of fields:
  
  
  
  In this case, the field has the underlying value options of "option_a", "option_b", etc.
  
  The _Selected and _Text values work in the same way as the Select One example above.
  
  The Select Multiple field also adds _SPText and _SPValue which contain values formatted specifically for SharePoint.
