Of course I refreshed the page every time. Apparently I got always an odd-numbered subject ID (I checked it in my raw-data files). My mistake.
Thank you for your help!!!

refresh* the page after each test run to get a new id. - See more at: http://www.millisecond.com/forums/Post.aspx?TopicID=11933&PageIndex=2&Task=PostTopicReply&ParentID=11933&Update=1#sthash.KZ2zRcuX.dpuf

But it's not finished yet...(Code: You can use trnd00000)

this means that *odd-numbered subject numbers* (1, 3, 5, ...) will receive the 1st condition, and *even-numbered subject ids* (2,4,6, ...) will receive the 2nd one. If you only ever enter the same subject number (1), you will always get the same condition and you should.None of this has anything to do with participants having to enter a subject or group number via the launch page. You simply ought to configure the launch page according to what you want (e.g. generate a random numerical id).
