Dynamo Introductory Video>Computational Logic 2

Hi all,

I have encountered an issue about my Dynamo logic is not updating in the Revit. In the computational logic 2 video, there is a step where change the lacing function to “cross product”, the family type specified will be laid out like a matrix in the Revit Interface. However, in my case, I am able to specify the item and place it in the Revit, but unable to update the matrix arrangement that displayed in Dynamo Interface in Revit.

Thank you for helping!

Here is an example
