Select list item: Attempt to get list item 6 of a list of length 5

[Sevlacnog]

Hello, when I test my app with MIT ai2 Companion I have a runtime error and I don't know where the error come from.
So, is there a way to have a marker on a block when a runtime error appear, to know where is the error?

I think I get what is the problem, is that possible to stop a For loop like that?

Do it this way(not tested but should work) -

I change it by using a while but thank you I will know it for future blocks

If you try to get an element from the list, it is always a good idea to check whether the index is larger that the length of the list. I cannot see from your blocks where that should be done. Also consider using
in your blocks, or
because this will allow you to handle lists with another length, that you may not know in advance.
