I am currently testing the potentials of using loops by modifying the “mask priming” template offered in PCIbex, since it has a loop in it. What I try to do right now is that whenever the respondent clicked on something that is not “F”, for instance they clicked on “J”, then a message would be returned to them saying that it is not correct, and that they should try again. I just kind of want to get the loop logic correct, and then I hope to apply it to a selector function. Is this potentially doable in PCIbex? I am more than grateful for your help and understanding.
