Select Elements on current level and add information on "Comment" parameter

[Harywijaya.2]

Hi All,

Apologize for my silly question but I stuck in my Dynamo even I have reads some post that relevant with my problems.
I make a dynamo to help me add information Underground on Comment parameter for pipes that lower than Level 0.
but I can’t select pipes based on their elevation that should lower than Level 0

Please advise and thank you very much

Hi mate

Based on your Dynamo, we success to select all pipes on “Level 1”.
Can we only select pipes that have elevation under “Level 1”?
example below that pipe middle elevation -100 from Level 1
