Change Type Parameter of Column

Rhino.Inside Revit

Hi Everybody,

I copy Column types in Grasshopper and I would like to change their Width and Depth parameter, but I cannot figure out how to access these parameters.
I hope somebody can help me.
Thank you in advance.

I think you need to access the type, not the instance: Shared Parameter Query - #4 by Japhy

It works now.
Thank you.
