Hello, I want to show a popup when one of my tag is true. I've tried binding the tag to ta custom property in a view screen and then do a under a change script: I added just: system.perspective.openpop(viewpath). By doing so, when I turn on the bool, I got an error. I would appreciate any feedback you guys have. ---

I also try adding this to the tag: ``` popupId = "checklist123456" viewPath = "Popup/Checklist" # insert your view path here logger = system.util.getLogger("POPUP") sessions = system.perspective.getSessionInfo() for session in sessions: for pageId in session.pageIds: logger.info("{0} | {1}".format(session.id, pageId)) if session.userAgent != "": if currentValue.value: system.perspective.openPopup(popupId, viewPath, sessionId=session.id, pageId=pageId) else: # note no viewPath arg system.perspective.closePopup(popupId, sessionId=session.id, pageId=pageId) ``` This works but it requires the user to have gateway homepage browser to be on in the background and the designer. ---

I get the gist; can you post the _exact_ script you had in the property change script on the session custom property? ---

Post the error as preformatted text to make it easier to read, please see [Wiki - how to post code on this forum](https://forum.inductiveautomation.com/t/wiki-how-to-post-code-on-this-forum/77831). You need to bind the tag you want to watch/trigger the popup to a custom property on either your perspective session or view, and then use a value changed script on that property to open the popup. If you bind on the session property, you'll need to use a message handler to send an open window message to the currently open view, which will need to have the associated message handler defined. ---

sure. It just this: def valueChanged(self, previousValue, currentValue, origin, missedEvents): system.perspective.openPopup("Popup/Checklist") I didn't want go further if this doesn't work. ---

> [@Long\_Vang](#): > > def valueChanged(self, previousValue, currentValue, origin, missedEvents): > system.perspective.openPopup("Popup/Checklist") Please put all code as formatted text so it's easier to read/retains indentation. You are not providing the required arguments to [`system.perspective.openPopup`](https://www.docs.inductiveautomation.com/docs/8.1/appendix/scripting-functions/system-perspective/system-perspective-openPopup). You need to supply a popup Id as well as the path to the popup view. ```python def valueChanged(self, previousValue, currentValue, origin, missedEvents): if (not previousValue or not previousValue.value) and currentValue.value: system.perspective.openPopup("_pChecklist", "Popup/Checklist") ``` ---

Thanks Mate. Got it to open the popup. How about when the tag goes to false and close out the popup? I tried the else statement but that doesn't seem to work. ---
