The situation is we have two sequential picture stimuli in each trial (pressing the button to change from the first to the second), which has been done with only the builder and a spreadsheet!
And we have 24 trials in total. We want to randomise the order of each trial, but we don’t know how. Could you please advise us with that? We have no previous coding experience, it will be helpful if it can be done in the builder only.
