Chatscreen error

When I go to my chat screen, it opens the messages and information correctly, but this message appears, why?

blocks part 1

blocks part2

blocks part3

someone help me :confused:


List indices in Kodular start from 1.
Somewhere in your blocks you’re trying to select item #0 from a list.


but messages to chat function start to index 0 right?

you are using set id to 0, use get number
