On-Line measurement (case 443)

I'm trying to do on-line measurements, but I haven't figured out how to do that.

I'd like to show a movie clip and ask people how much they enjoy the video clip over the time as the video plays.
I chose "on-line rating" for item type,
and I entered (p7) in the parameter(s) and set a 7 point scale.
And I also inserted a video clip in "backvideo" and added (w-2) in the parameter(s). (so, in the parameter(s), I entered "(p7) (w-2)")
But it doesn't work. anyway.

Could you let me know how to do it?

Online rating scales display over the subsequent item. As such, you need two items to achieve what you describe. The first is the online rating scale (with the p7 parameter). The second, which should come immediately afterwards, is a movie item with the video file (and the w-2 parameter). These two in combination should play the video with the real-time enjoyment scale displayed. Let me know if this doesn't fix the problem.
