Hello

I´m little bit confused with simple problem to filter one list with individual numbers.

I have one list consist from numbers like: 0, 1, 2, 3, etc. but the lenght of the list differs. Sometimes there are 2 items, sometimes 8 items etc.

Then I have numbers that I want to cull from this list. For eg.: 2, 3, 5, 6, 9, 50, etc.

And all I want to do is, that it cull these numbers, if they appear in the first list.

I think the problem are that the lists are not same lenght… Searching some example, but I did not find anything to solve this yet. If anyone could help me with this, I hope simple function, I would really appreciate it !

Thanks
Tom

Can you share the definition? I guess i know whats wrong, but it will be much easier with your gh file
edit: in case you can’t, pay attention to match your tree structures, as well as converting all your data streams to “number” type, using num container
