Thank you.
Oh, that's makes things much clearer, thank you! And, if you don't mind, one final question – would it be possible to refer to these blocks (the ones that were shown) later on in the survey by their embedded metadata? So that I could later on once again show these exact blocks again to the same person?
Thanks, that looks like something I need! However, I can't really figure out how to set a unique id for each block. And should you do it _before_ the randomization? Since judging from your screenshot, the randomization block already includes FirstBlockSeen variables, while it seems that Block1/2/3 variables were created beforehand, right?
