A+b dropping values obtained from unique keys

I am trying to use unique keys obtained from grouping rooms by their Comments parameter to create a name for new views. I get sorted values as in here unique_keys and try to combine them with a prefix of “M”, by plugging into the code block to the right (“a+b”)

. At this moment one value gets omitted (“176”) and I don’t know why.


It would be easier if I could see a bit more of your graph, maybe with more previews? :slight_smile:

Just incase you don’t know, using File>Capture when you can read the text from one node will export your whole graph as an image with readable text…

I’ll have a guess in the meantime :slight_smile: you have removed an index from your repeated list, maybe that doesn’t give enough repeated items to add to 176? (Or is it 174?)

Hope that helps,

Of course, my bad. The lists were of different length. Thank you for showing me my mistake :slight_smile:
