Matching two lists to get "boolean" values

[Ahmad_Saad]

I have two lists of numbers, one of them is contained within the second.
I am trying to get the mask values in order to use it later to get some specific elements; but it gives me “false” values all the time.
Any suggestions?

**the list at the left is a room “volume” values; and the one on the right is just a range of numbers.

Thank you

Looks like the “equal” node was the reason!
I just used “list.ContainsItem” and it worked.

I was trying to get the list of rooms where is the volume value between 10 and 100

Here is how it worked:
