JONL4(I) is reaction time and JONL1(I) is indexed each time there is an error. So if things are good and the child has a reaction of one second "and" does not make a error in this loop pass then the child should see VERY FAST! on line six of the graph screen . If the child has been fast but made an error then the else command should display VERY FAST WITH ERROR. When I put this bad boy, inside a working program, It blows me completely of the program. I guess it is time for the professional programmers, that is you and this amateur programmer should wait in the wings for your response!
If ⌊JONL4(I)=1 and ⌊JONL1(I)≠I
