Hello!

I am designing an IAT experiment using the trial version of Inquisit Lab 6 for my thesis, and was wondering if there was a way to automatically and randomly assign participants to one of two conditions without having them enter the group number, subject ID and session number? I have attached a screenshot of the screen I would like to "get rid off" from the participant's point of view.
 
I followed the directions on this website https://www.millisecond.com/support/docs/v6/html/articles/websubjectnumbers.htm, but it didn't work. Is it because I am still using the trial version of Inquisit Lab? 

Any help or clarification would be much appreciated!

Sincerely,
Harini
