I thought since release 2022.1.1 staircases can be ran online but it seems this is not the case?
This is for interleaved simple staircase
Did you ever get a response to this? I am getting the same error, using 2022.2.4.
The staircase had not been ported to Pavlovia yet. I’m afraid, at this stage, you need to do the js coding yourself.
