HelloI have 30 Amazon voucher codes and instead of e-mailing them to my 30 participants I would like my survey to randomly show one code to each participant. If I set up randomization that 1 of those 30 codes is displayed there is a chance that the same code will be shown to two different people. So the problem is that once one of the codes is displayed by one participant it can't be shown again to another participant. Is it possible to set it up somehow? Thank you for your help!

Did you try by enabling "evenly present items" and mention 1 which will just show 1 code.
