List replacement mystery

Hi all,

I'm currently having some weird results with the list insert component, but it's maybe because it is not the right logic for what I'm trying to do: I would like to replace precisely defined entries (numbers) in a list, by some other numbers (in a different list) using their index:

For exemple, replace the list item n°5 by this number.

I saw that there are already some topics on this (sptember/november) but I did not found solutions in it... Here is the thing:

The values are coming from a simple comparaison between to list: when a value is found then it gives its index (and then I would like to use this index list to replace some values in a similar list):

"Search "123" in this list" --> "Oh, there's one in the index 24" --> "Ok, so say to this list that it has to update with this new value at the same index".

If someone has a clue...

Thanks for your help,

hey, that's a great component!

i would have a comment though - it doesn't work if he receives a null list in the index hook, which means he must at least modify 1 object, which makes it less parametric (in my case i have this slider that tells the algorithm what percentage of a group of objects should suffer an alteration, and if i want to make that number 0, it gives an error since no indexes are provided)
