The exclusive option that was added to questions is fantastic. I have a few surveys that need this option on the array style questions. I have not modified lime survey's code since a much older version which is, needless to say, very different from the current code.

I was wondering if anyone had added this exclusive option to the array style questions before or if they knew what code needed to be modified. It's under the show advanced options, logic section, but I can't find where that code is stored. Any help on this would be GREATLY appreciated! Thank you!

Question attributes for each question type are handled at "qanda.php" file.

Maybe there is some additional code at the survey engine. Depending on the survey mode I think the files to modify are "question.php", "group.php" and "survey.php".
