More information

NOTHING is a special value often returned by a function when it is unable to return a value.

This lets you check if a value is NOTHING. The main use cases for this is that a variable’s value will be NOTHING if no value was entered/selected for the following questions and they were marked as optional:

  • @DATE_QUESTION
  • @NUMBER_QUESTION
  • @PICK_ONE_QUESTION
  • @YES_NO_QUESTION

If you want to display something special when nothing was entered for them, you can use <# @IF(ISNOTHING(my_var)) #> ... <# @ENDIF #>.

If, on the other hand, you want to display something only if a value was entered, you can use either:

  • <# @IF(NOT(ISNOTHING(my_var))) #> ... <# @ENDIF #>
  • <# @IF(ISTEXT(my_var))) #> ... <# @ENDIF #> for a @PICK_ONE_QUESTION with text values
  • <# @IF(ISNUMBER(my_var))) #> ... <# @ENDIF #> for a @NUMBER_QUESTION
  • <# @IF(ISDATE(my_var))) #> ... <# @ENDIF #> for a @DATE_QUESTION

More information about NOTHING can be found in its documentation, see below.
