Dear all , Dear Dave,

i run a web experiment (scripting is in inquisit 5.)
subject id : random without replacment
group id: sequential
number of groups: 10

before i run the ten counterbalanced expts where subjects are assigned to their specific group based on their group id, i wanted to run 3 equipment test experiments that always preceed the 4th (ten counterbalacned expts):
Till this day (and from my experience this was the observed behavior in my other scripts - lab & on-line) the expt execution order was determined by the order of expt listing in the script. (like in the example below).
the problem: the first expt is always executed first, but the 2nd and the 3rd somtimes are executed after my 4th expt (10 conterbalanced expts).
But it never seems to go like 1st, 2nd , ten counterbalnced , 3rd or any other random order....why is that? any help appreciated.

Cheers Kuba
i've also attached the script (a bit messy inside...sorry for that)


<expt>  ///// first fixed as i hoped////
/ blocks = [1=testsluchawek]

******** checks if headphones are properly put on
******** check based on responses
<expt> ///// second fixed as i hoped////
/blocks = [1=testsluchaweklewaprawa]
</expt>


******** general intro to the experiment
<expt> ///// third fixed as i hoped////
