Title: Fixed issue #8500: Example surveys not properly importing

(1) array_filter and array_filter_exclude in this survey had underscores -- fixed and validated
(2) Note - it would be nice if the survey logic file or survey design mode showed an error when user selects undefined variables for array_filter or array_filter_exclude
