Hi all,
I am a first time user of Inquisit, and am trying to program a study that displays a list of eight variables/questions (strong and weak), that are selected at random so the list is different for every participant. So for each variable, I have created an item that contains both the strong version and the weak version of that variable, and trial with each of the variables as the stimulus frames. What I am trying to achieve is that a participant is presented with a list containing randomised versions of the variables (so they could be presented with three strong and five weak variables, or six strong and two weak variables, and so forth), however I cannot get it to work. Please let me know if I am missing something in my script or if I have programmed something incorrectly. Thank you!

Here is my script (I have replaced the questions with just 'strong' or 'weak' for simplicity here, because they are quite long).

<parameters>
/taskduration = 300000
/timereminder = 60000
</parameters>

*****************************************
STRONG AND WEAK VARIABLES (Ordered 1. Strong 2. Weak)
*****************************************
<item ArrayPrior>
/1 = "Strong version"
/2 = "Weak version."
</item>

<item ArrayField>
/1 = "Strong version"
/2 = "Weak version."
</item>

<item ArraySpecialty>
/1 = "Strong version"
/2 = "Weak version."
</item>

<item ArrayAbility>
/1 = "Strong version"
/2 = "Weak version."
</item>

<item ArrayOpinion>
/1 = "Strong version"
/2 = "Weak version."
</item>

<item ArrayBackedUp>
/1 = "Strong version"
/2 = "Weak version."
</item>

<item ArrayConsistent>
/1 = "Strong version"
/2 = "Weak version."
</item>

<item ArrayTrustworthiness>
/1 = "Strong version"
/2 = "Weak version."
</item>
