My gut tells me this isn’t possible, but throwing this out to the community any way in case there’s something obvious I’m missing.
I have two Choice Displays that show the same set of display choices and send the same set of values… but they send them into two different columns of the spreadsheet. Part of my app’s game mechanic is that players much choose exactly two things (no more and no less) from a master list. I do this with two choice components. I imagine at some point we’ll have a multi-choice component and hopefully it’ll provide a way to limit number of options. Until then, this is how I’m doing it.
Problem: I can’t prevent players from choosing the same two things from that master list, and rules are that the two things need to be different. I have a script running that detects if the two values are the same and clears them out (forcing the user to resubmit those two choices before their submission is officially accepted), but this is clumsy and I’m wondering if anyone has come up with a way to filter a choice display to not display an item already chosen in another choice display.
