When someone is filling out a survey where the special field - name (question type 13) is and you have filled out less than 3 values (even if you were to hide the title field) it would not save the values put in.
/home/vve010/public_html/components/com_communitysurveys/models/response.php#934
This code checks if al 3 fields (no less, no more) is filled in before it is able to save.
Please remove this if statement, why would it be relevant how many fields for question type 13 you would fill out before saving?
