I am currently working on using Perspective for a mobile app. My current goal is to have a “Confirm” prompt appear after a user enters in a new value for a field. Since I am sure the fancy “thought balloon” for the One-Shot buttons is only available for that component, I was going to try using system.gui.confirm script in an event. The closest event I am finding are “onCompositionEnd” in the Text Composition Events, but I am not sure if it is triggering by touching “Done” or “Return” on my iPhone on-screen keypad. Am I using the correct event for this, or are the Text Composition Events intended for other components? ---

Well, leaving aside the problem of which event to use, `system.gui.confirm`, despite the namespace, is not a function that will work in Perspective; only in Vision. Within Perspective, you’ll have to ‘roll-your-own’ popups and open them, and retrieve the value(s) the user submitted. ---

I would include a valueChanged script to open a Popup. Depending on what actions you want the confirmation Popup to provide, you’ll probably need to also set up a message handler on the Numeric Entry Field, as well as place some system.perspective.sendMessage calls on the Popup buttons. ---

Thanks for the clarification on system.gui.confirm, as well as a proposed solution for my issue. However, I am not seeing a “valueChanged” event for the Numeric Entry Field component, instead the closest event being “onCompositionEnd”. I tried adding a Logout action to this event, but I could not get it to trigger (assuming that it is triggered when the field is updated upon touching “Done” or “Return” on my iPhone on-screen keypad). Is the “onCompositionEnd” event supported in the Numeric Entry Field? If not, is there a different component I should be using? Thanks for your help. UPDATE: Upon further testing, I found that the “onActionPerformed” event of the Component Events triggered after updating the Numeric Entry Field’s value. I will continue on with your suggested method. Thanks! UPDATE: I just found a more detailed description of that suggested method [here](http://forum.inductiveautomation.com/t/getting-confirmation-from-a-user-in-perspective/30494/2). Thanks again! ---

The change script can be found by right-clicking any property in the Property Editor. If there is no change script currently in place, you’ll see “Add Change Script”. This script will execute whenever the property changes. ![Screen Shot 2020-07-01 at 8.17.06 AM](https://us1.discourse-cdn.com/inductiveautomation/original/3X/1/c/1c42ca8becd3a4e6f1395f76106caf61adb6c9ca.png) ---

Just what I needed. Thanks!
