Are you super admin ?

I'm pretty sure I'm super admin as there are no other users. I'll log in and check soon. As well as paste the error messages of when I put in script.

I'm the only user and it says administrator next to my user. Not sure where to check if super admin but it should be.

I'm attaching screenshots of the issues. First 2 images are when I pasted the script in a text display question. When saving, it just breaks the page and doesn't save it. The last image is when I pasted script into End message.

LimeSurvey version ? With 4 : you must update

Was on Version 4.3.0+200616 but I've given up on it and have gone back to 3. Because I could not figure out how to even reorder my questions! And also the documentation does not refer to ver4, only 2 and 3.

Anyway, I've gone back to 3 and I'm testing passing the parameter to another page where I will script everything. So far, I've managed to pass the parameter. Still testing...

So my solution now is to pass the parameter in the end url which goes to an external page where I can do the scripting. It's working well, thanks everyone for your time.
