I am using the script below for a mouse click script on a LED Display, I have a custom property named WindowPath. But I get an error saying the window doesn’t exist.

```auto
window = system.nav.openWindow(event.source.parent.WindowPath)
system.nav.centerWindow(window)

```

Try printing `event.source.parent.WindowPath`.

I changed the custom property name and it worked?!

```auto
window = system.nav.openWindow(event.source.parent.Path)
system.nav.centerWindow(window)

```
