A simple if statement in a code block will do: val == “-1”? v: “o”;

I’m a little confused; I set up this ReplaceByCondition as below, but it is telling me that the “condition” input requires a Function input as opposed to a boolean.

The function should be something like the < node without the X input (or whichever input is the list in which you want to replace something).

Without seeing the input context we can’t directly help if you’re looking for something else though. Perhaps some design script ali g the lines of a<5? “NaN”: b;?
