I’ve never had an issue displaying the current Username in a Vision Client. However, in Perspective I’m getting a Null value when completing a binding to a Custom Tag in a View’s Root for the [System]Client/User/Username. For an additional test I also tried binding a Custom Tag to the [System]Client/User/OSUsername and get a Null value warning with it as well. When I go to the Tag Browser to view the current [System]Client/User/Username my user name is there with all the additional User Tag Data. What am I missing? Is there something additional I must do with binding in Perspective for System Tags? Note: I haven’t had any issues with bindings for other tags whether they be OPC or MQTT tags. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/a/2/a22512348596a11f82b4378fe87b95efc9e9b813.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/7/1/716205cbe63e5286ee6fbb6cefc99e040c2bafbb.png) ---
