Hi there, I'm very stuck. I have a pool of 6 images and two different tasks. I want it to be that each participant only sees each image once across the two tasks (without replacement). At the same time, each task shows three different images separately, followed by some questions. There are two levels of randomisation:The order of the tasks (i.e. task 1 first, or task 1 second) Dividing the images up between the tasksAt the moment, the 6 images appear in individual blocks with the relevant questions for each image (e.g. image 1 appears in the block 1A) I've attempted to set up a randomiser that presents 3 of the blocks while embedding the choices. How can I get the second task to display the images that haven't been shown already? Any advice would help so much!!

The first issue I see is that your task order will always be equal to 2, because its in the same "Set Embedded Data" Block. In the randomizer make two such blocks, in one set task order to 1 and in the other to 2.I couldn't understand the other image related issue.
