The countChecked function returns the number of items selected in a checkbox (multiselect) question. It can be included in conditional statements or used to return the number of options that were checked in a checkbox question.

Note: The above example uses a Perl code block to allow the countChecked function to render the number checked on screen. Without this it, would render the text on screen rather than evaluating the function. For more information, see Piping with Perl.
Tip! countChecked also allows programmers to specify a range of options to be counted. countChecked($Q1,1..3) will return only the number of options among the specified options 1, 2, 3 that are checked.
