Welcome to the forum. Please edit your question title and select Vision or Perspective from the tag dropdown. You've said "window" which implies Vision. (Perspective uses "views".) Tip: the FAQ "Keep it tidy" section asks that we don't add signatures to posts. Your user name is applied automatically. ---

Please share more information about your application: - Where does the string come from? A constant? A tag value? Some expression? - Is the text field connected to something? Or unbound (for scripted custom handling)? - Does the source of the field depend on the button that opens it? Where multiple buttons might open this window with different sources? ---

The string comes from the button that opens it. That string is used to filter the data on window. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/6/3609a3f5a72d0ec798b56e966da7893894da8cb4.png) Current button script: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/5/e5309a126d8e36c871abe42b1999d0906b2fcfc2.png) ---

That's not a window. You have a container pretending to be a window/template. You'd use `system.nav.openWindow()` to open a window. Since it isn't a window, and therefore everything is in the same actual window, you can use layers of `.getComponent()` methods to reach that text field, and assign to its `.text` property. Within your button script, you can use the property tool (on the right) to help you construct that set of methods. ---

You are a legend! ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/5/35d47f664770273a5fe9030f00edf08d60a63b15.png) I got it. I am an end user and learning the scripting in ignition. @pturmel Thank you so much.
