Hello Forum,
This is my first try with Dynamo.
I am trying to fill in the values from excel for the parameter “Crew_Name”.
This is the error I got : Warning: Internal error, please report: Dereferencing a non-pointer. (3f47aacd)

Connect the ALL ELEMENTS OF CATEGORY node to your ELEMENT. SET PARAMETER BY NAME.
The get parameter node outputs a parameter value not an element.
In addition you also need to have the node listdropfirst item i think is the name to drop the crewname from your excel to mstch your element id.

Outputs the parameter value not an element id
The node setparametervalue needs element id to work.

Sorry I was not clear with my request. I am trying to use a legend to control the values assigned to a parameter:
I have 2 shared parameters in Revit : Element Description (Values W1;W2;W3) and Crew_Name (Blue ;Green; White)
If element description is W1 the Crew_Name should be Blue, (W2= Green, W3=White)
The final expresions that I want to write is something like: lookup to excel table for W2 and copy the value from second column (I.e. Green ) to Revit parameter Crew_Name where Element Description param has value W2
