Randomizing image without repeating in blocks?

Is the only difference a question in a text component? If so I would add a loop counter in Begin Experiment (loopIdx=0) add one to it each loop (loopIdx+=1) Then change the text component when loopIdx=10 text_1.text=‘new question ‘ Previously I would have used .thisN to count the loops but I’ve stopped using it because it has stopped working online

20 trials among the 150 rows in Excel

Since trials.thisN doesn’t work any more, you could set trialIdx=0 in a Begin Experiment code component tab and then add the following to the End Routine tab. trialIdx+=1 if trialIdx == 20: currentLoop.finished=True
