Popup open in multiple window

HI, I’m trying to figure out a way to open the same popup in every window of the project at the same time. The popup open when a certain property of a tag is=1, so actually the popup only open in this specific page. I would like to open it in all window as a master warning you can see wathever what you where doing. Does somebody could help with that?

Assuming you are using Vision, you can use a client tag change script to do this.

if newValue.value:
	window = "popup"
	system.nav.openWindow(window)

It works, thanks! I didn’t know what client tag change script was, its usefull.
