Need Help Getting Index of Matching Values in Lists

I have two lists and I want to get the index of the items in List 1 that have equal values in List 2.


As you can see Index 80 in List 1 matches Index 0 in List 2. I would like to filter List 1 to only show which values that are dupilcated in List 2.

@Robert.todd Looks like you are comparing strings against numbers.
Put a String from Object node after List 2 OR remove it after List 1.

That seems to give me the same results

Add a Math.Ceiling node in between like this:

That fixes it. Thank you very much.
