Can you tell me if only admin can add javascript code to question text? If not, can you tell me what rights do I have to set.
Thanks.

Hi,

Filter HTML for XSS: By default your survey manager will not be authorized to use dangerous HTML tags in their survey/group/question/labels texts (for instance JavaScript code). This is intended to prevent a survey operator to add malicious script in order to have a true admin raise his permissions on the system. If you want to use any script objects like Javascript scripts of Flash applets in your surveys you will need to switch this off (Specific script for video hoster can be used). The XSS filtering is always disabled for the superadministrator. In order to see the effects of XSS filtering, it is advised to use a regular user account.

Thanks to both of you for your quick answer.
