Randomisation

@FaizaAli can you do a screen shot of these questions? I'm having a hard time visualizing the setup...I can create a test on my end based on how you've got them setup.

So say the 6 nonmeat, meat pairs are mushroom sandwich , mushroom burger cauliflower slice, cauliflower steak soy pieces, soy meatballs butternut bake, butternut casserole tofu bite, tofu sausage brocolli stew, brocolli hotpot So there are overall 12 dishes. I want to present 1 of each of these dish pairs randomly (i.e show them mushroom sandwich then cauliflower steak then soy meatballs ...) so there is a total of 6 dish names presented to each participant. To make the study balanced i need to make sure each participant acts as their own control so they have 3 randomly from the nonmeat dish names and 3 randomly from the meat dish names. But to avoid any confounding issues i dont want any 2, both from the same pair, ie mushroom sandwich and burger to be presented to the same person. Does that make sense? It's a lot of combinations so im not sure if i can set it up manually.
