Baluster Location irretrievable/coming up short

My goal is to find the location of each baluster on my stairs, then create extrusions from that bottom point, to a specified level.

However I cannot seem to get the location of each instance, they all say 0,0,0…

Any insight would be greatly appreciated, this is my first Dynamo project.

Thank you!

There are multiple ways, Here is one of them.

Legend! Thank you @_Vijay

Hi again!

Any chance you know why Horizontaldown is coming up null?

Thank you!

Nevermind! It fixed itself…
