Filter list with minor and equal conditional

Hello, I do not know why I can not filter a list using the logical operator of equal minor, it only allows me to use the equal.

f

Need to see all of the input lists and their data structure to know what the issue is here.

I would check your ‘Get Parameter’ parameter results for an empty or null result and then filter it accordingly.

I believe @i.shaw is correct in that you have multiple types of data here. Note that by adding any non-numerical value to the front of a list results in a ‘null’ when using any mathematical logic, as asking if “A” > 1 is comparing across types, but using the Equals node (not the == node) you’re asking is this the same object type and the same value?

You can confirm this is the issue by placing a List.Unique values after the <= node, and you’ll likely see a list of {true,false,null}.
