Pattern family hosted on a mass surface Instance parameter Greyed out

I was following an old kinetic facade tutorial from:

This was done using Revit 2015 and an old version of dynamo.

As im using 2017 and dynamo
Following the tutorial it to the letter is not possible as most of the nodes have been changed or do not work as expected.

I modeled and made the family along with the parameters and created a new project and applied it to the mass surface now i am able to select it but not change the parameters as the parameters are Grayed out and in dynamo i get Read only error.

in the file i uploaded i am able to select it and change it in project file and dynamo because i changed the parameter “NCP” into a type parameter
** but i want it to be a instance Parameter and set the “NCP” parameter induvidually**
