Hi there,
I am trying to create a sort of attention check block for participants to test their understanding of the task. This block is titled "Attention Check". I only want them to proceed with the rest of the study if they get all 4 questions in that block correct. I already set up the display logic to be such. In addition, if they get a question wrong in the attention check, they should be brought back to the first block, which contains the instructions. There are two conditions, thus two different blocks -- "Dispersed condition" and "Concentrated condition". However, I am not sure how to create this loop of them being brought back to that block till they get all 4 questions correct. 
Once they do get it correct, will they be brought to the next block. I have attached some screenshots to further explain what I've done.
