Node error | Generate test points by by grid size

I don’t know if this is a easy to solve issue, but did anyone have any luck with the error coming from the nodes?

Not that I know the answer but I hope someone else can help you if you share more information about the version of Dynamo and Revit.

I was using Revit 2020 + Dynamo Core / Dynamo Revit

This is the current setup, I try to follow the setup from the example file and was have similar trouble with the error message from site locator. Similar error found earlier (Invalid literal for float(): DynamoForRevit)

I was modifying a tutorial from Autodesk University to suit my needs…

I am not very experienced with code or dynamo at the moment.
