ReferenceError in expInfo

[yang]

URL of the experiment: Pavlovia

Description of the problem:
I got this error when running the online experiment

I check the parameters in the builder

and Data filename as below:
u'data/%s_%s_%s' % (expInfo['participant'], expName, expInfo['date'])

I am not sure what causes this error, any suggestion will be appreciated!

I’ve just sent you an email about this. You had exp1nfo instead of expInfo in your completed URL but I’ve just fixed it.
