Configured a script in ok button which one attached in pictures.

Screen shots are not as helpful as you might think, please also provide preformatted code as well. The path to one of your text field components is not correct. I can’t tell which one as you’ve cut off the line numbers. Use the property selector to insure you have the correct path to the components. ---

@govind You can check the component's path. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/7/c7468dee012148da2dfb42a49009e2a062c41e9b.png) drag your component path from the insert property reference for more information see the below screenshot: ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/e/5/e5b2b494de551c87f76edaecff1e49c62f82cfae.png) ---

I think you had copied the script from Manual but did not made any changes according to your project. ---

Thank you, Yes, I copied the script from the manual and did not configure the property. So, configure the property as per shared by you. It's working .
