II wanted to see if I did/understood something wrong because this is what the preview looks like now:
 

Did you look at your post? Don't paste images, use the editor to insert them.

Did you try importing my survey? This is why I provide them.

Do you have permissions to insert JavaScript?

- manual.limesurvey.org/Workarounds:_Manip...tc..29_in_LimeSurvey

Yes, I edited the post.
Unfortunately I cannot import your survey nor anything because I am not the site admin: we are doing this survey for a University project and our professor is the admin.

But your screenshot looks as if you are not allowed to enter javascript code.
Ask the admin of your LimeSurvey installation.
The XSS filter seems to be activated.

If you have the rights to do this you only
add the script to the question text in source code mode.
And  create a subquestion called "Others"

I will ask her, thank you
