There are many posts already, perhaps this one will be helpful, [Show a popup in perspective on all clients if a value changes](https://forum.inductiveautomation.com/t/show-a-popup-in-perspective-on-all-clients-if-a-value-changes/61133) By the way, you don't have any script. ---

Welcome to the forum, Francisco. For anyone to help you, you need to show, 1. What you did. (Post formatted code - see [Wiki - how to post code on this forum](https://forum.inductiveautomation.com/t/wiki-how-to-post-code-on-this-forum/77831) - and post a nicely cropped screenshot if you think that will be helpful.) 2. What did you expect to happen? 3. What happened? (Error messages, etc.) Otherwise everyone is just guessing. ---

Tags are outside your project. Tags know nothing about your project. Tags don't know if your project is open or not. Tags know nothing about session properties in your project. Try this: - Create a session custom property on your project. - Create a tag binding on that custom property. - Create an onChange event on that custom property. Put your navigation script in there. ---

Make sure that you are consistently using one tab character to indent, not any mixture of tabs and spaces. You can right click in the script editing area and select 'Appearance' -\> 'Show Whitespace' to see the invisible indentation characters. ---
