Select list item: Attempt to get item number 1 of a list of length 0:[]

Hi, I am trying to avoid redundancy in my App by using a procedure, when I run the procedure i get the following message:

Select list item: Attempt to get item number 1 of a list of length 0: []

I have tried to to sort this out but can’t figure out what is going on since the list I am using is not empty. I need some advice, I am trying to develop an App to help people during this pandemia. Any help would be greatly appreciated

@Alberto_rojas_lefort

the list I am using is not empty

Eventually "myList" will be empty:

My guess is "myList" is shorter than "siguiente".

Thank you very much, I’ve found out what I was doing wrong, the way I approached the logic was wrong.
