Double conditional function to exclude "0" & Empty values

[segatakieddine]

Hello
i want to use the filterbyboolMask to exclude “0” and “Empty” values of a shared parameter that i have created for wall elements in Revit. i could not find out how to create the double conditional function especially with the Empty value !
Thank you !!

Hi,

use a second == node and feed your list in the y and create a codeblock that says “true” for the x.
true remains true, zero’s and null values will be false.
