You're better off arranging the three "instances" as actual items under a single <picture> element each. Then just randomize the position. For the randomly selected sound, also use a single <video> element with the two audio files as its items.

<values>
/ kaiseeposition = 0%
/ regliposition = 0%
/ whichisitem = 1
</values>

<block exampleblock>
/ trials = [1-3 = exampletrial]
</block>


<trial exampletrial>
/ ontrialbegin = [
values.kaiseeposition = list.hpos.nextvalue;
values.regliposition = list.hpos.nextvalue;
values.whichisitem = list.whichis.nextvalue;
]
/ stimulusframes = [1=kaisee, regli, whichis]
/ inputdevice = mouse
/ validresponse = (kaisee, regli)
/ iscorrectresponse = [(trial.exampletrial.response == "kaisee" && values.whichisitem == 1) || (trial.exampletrial.response == "regli" && values.whichisitem == 2)]
</trial>

It worked! Thanks so much!

Hi! After applying this logic to other counterbalancing conditions (I have 4 total represented by 4 different experiment elements, 2 of which I've attached here because they aren't working), I came up with a few issues. Here's the code, and the issue/errors I'm having are at the bottom of the code.

These are the errors I got when expt PINT_novel3:









These are the errors I got when I ran expt PINT_novel4:









This also appeared in PINT_novel3:



The same thing happened in PINT_novel4. Also, there were only 2 trials that came up in the second test block instead of the 3 trials I programmed for both experiments PINT_novel3 and PINT_novel4.

Not sure why I'm getting these errors considering the name of the mp3 file is exactly the same, and it's in the correct folder, and it is working (I used the same audio file worked for experiments 1 and 2). 

Please let me know if you know what's going on.

Thank you!

Please do not past entire scripts into a posts body. Instead, please attach the script to a post using +Insert -> Add File.

In addition, if your script requires any external files to run, provide those files as well.

One obvious thing:

<item whichisitems_veebogazzer_6>
/ 1 = "whichis_veebo.mp3"
/ 2 = "whichis_gazzzer.mp3"
</item>

would appear to be a typo. I'm fairly certain the file is actually called "whichis_gazzer.mp3" with two z's, not three.
