Instructions appearing twice and counterbalance failed

Hi Jeremy,

I just got started with PCIbex, and am facing a problem possibly related to counterbalancing.

Here is the story: There are 2 Groups in my stimuli.csv, each containing 40 items. I was hoping my participants to see 40 stimuli from either of the stimuli groups and 80 fillers. I tried this as instructed, by sending different links “https://farm.pcibex.net/p/zQTNwJ/server.py?withsquare=0 & “https://farm.pcibex.net/p/zQTNwJ/server.py?withsquare=1”. However, people are still seeing all 80 stimuli from both groups.

What’s more, participants are seeing all the instruction trials and filling in their infomation twice before the experiment starts.

I wonder if you may let me know what’s going on so that I can fix it. Many thanks for your time!

This is the link of my demo: —-> https://farm.pcibex.net/r/ARgwvG/

Below is my code:

PennController.ResetPrefix(null);

PreloadZip(“https://nianpoproject.s3.amazonaws.com/fil_sentences_02.zip”)
PreloadZip(“https://nianpoproject.s3.amazonaws.com/exp_sentences_02.zip”)
