You are using Perspective syntax in a Vision script. This won't work.  
Select the property you want using the Choose Property button on the right side of the Script Editor window.

You are asking many questions with little understanding. I think you need to spend more time studying the videos at [https://inductiveuniversity.com](https://inductiveuniversity.com).

Or check the user manual, another good resource.

The manual literally has an example, similar to what I posted.
