How to obtain the value of an item of a list


I need help. I would like to obtain an item of a list by its index but this is shown as a list, I want only the value (50 as number not in a list).

Thanks for your help.

Note the effect based on list depth:

Thank you, I solved it doing a double GetItemAtIndex as you show me.
