Group: Forum Members Posts: 8, Visits: 23	I have 18 blocks of trials. Each block goes for an ever shorter duration. I am trying to provide feedback on which trials were identified with an accuracy of 80% or more. I have tried a variety of different codes with no success. The last one uses the list function: <page end> ^^^ Thank you for participating in this study ^^^ You were able to achive 80% for the following durations <% list.mylist.items%> ^^^ You might like to record this information for future reference ^ If you have not already completed the Variable stimuli study, please do it now. <list mylist> </list> I used the following instruction to add items to mylist (the second is set (300block) is w: <block 300block> /onblockbegin = [values.reach=300] /skip = [values.skipp==1] /trials = [1-5 = noreplace(300up, 300down)] /onblockend = [if(block.600block.percentcorrect<70) list.mylist.insertitem("300 ms", list.mylist.itemcount + 1);] </block> Nothing seems to generate a response in the 'page End' text.
