You want [Member Index]. [Item Index] is an awkward component which doesn't test for value equality but memory equality. So instead of comparing two numbers to see if they have the same value it compares two numbers to see if they are stored in the same location in memory.

[Item Index] does two things that [Member Index] can't:

  1. It works on all data types, not just simple ones.
  2. It can differentiate between different instances with the same value.

These are features though you will rarely need.
