The array filter tool tip says "The tool tip says "Enter the code() of Mutiple choice question(s)(separated by semicolons) to only show the matching answer options in this question" . It would be very useful if it work the way as indicated by tool tip. But actually only question id are supported in this filed. Please let me know if here I can enter the comma separated codes as well.
Sorry I was referring "question code" as "question ID". Anyway please let me know the results of using more than one "question code" separated by comma in this field.
