Group: Forum Members Posts: 11, Visits: 117	Hello, I find myself with two item elements: one has 15 items, the other one 4. The one with only 4 items is initially empty and filled during initialization. Now, i'd like to display all 29 items randomly. Every item should be displayed, but none of them twice. How do I do this? I tried list elements, and various noreplace() everywhere, but I seem to miss the point. <item speakerselect_1> </item> <picture speakerselect_1> / items = speakerselect_1 /select = noreplace / size = (40%,40%) / position = (50,50) / valign = center </picture> <picture speaker_2> / items = speaker_2 / select = noreplace / size = (40%,40%) / position = (50,50) / valign = center </picture> <item speaker_2> /5 = "20.jpg" /6 = "21.jpg" /7 = "22.jpg" /8 = "23.jpg" /9 = "24.jpg" /10 = "25.jpg" /11 = "26.jpg" /12 = "27.jpg" /13 = "28.jpg" /14 = "29.jpg" /15 = "30.jpg" /16 = "16.jpg" /17 = "17.jpg" /18 = "18.jpg" /19 = "19.jpg" </item> <trial environment_1_figure> /stimulusframes=[1=speakerselect_1] /trialduration = 1000 </trial> <trial environment_1_ground> /stimulusframes=[1=speaker_2] /trialduration = 1000 </trial> <block environment_1> / trials = [1-19=noreplace(environment_1_figure, environment_1_ground)] </block> This is not a working example, but I hope that makes it clearer. Thanks a lot!
