Millisecond Forums

Hi,
I have a study where a video plays and after every second a recording is made of the joystick.x position.  This works fine, but now I'd like to add in at the end a readout to participants of their highest and lowest ratings.  However, whenever I try to do this, it only seems to report whatever the last position of the joystick is.  I'm sure that I'm missing something simple.

So far the working part looks like:


<trial 1sectrial>
/ inputdevice = joystick
/ timeout = 1000
/ validresponse = (left, right, noresponse)
/ ontrialend = [expressions.rating]
</trial>

<expressions>
/ rating = joystick.x
</expressions>

<block videoblock>
/ trials = [1-96 = 1sectrial]
/ bgstim = (video)
</block>

I've tried various uses of expressions/values but not sure what I would need to add to get the max/min out of those 96 trials.

Thanks in advance!!
