So I'm making Sushi Go, a card game, on Scratch and I've run into a problem. See, in the game, you pass hands to the left at the beginning of each round. Additionally, in another script, I have code to pick out specific cards from the hand that the player/computer chooses. The problem is that I can't put a variable in the dropdown list spot in the picking out cards script, so there is no way to rotate hands. It makes a lot more sense once you play the game.

You see, I don't understand the concept of the game, because once I run out of cards, and I press any number key, it says “numbers 1-0 only.” Is that a glitch, or have I lost the game?

and I'm talking about Catalystix's version of the game.

I don't know. I just dumped the code into my game this morning and haven't been on Scratch for four hours so I haven't adapted it fully yet. I don't understand how it works fully yet, but I'm working on it.
