Wix expanding text and developer debug

Hi Wix,
I am trying to do the code for an expanding text button and while in preview mode I have this error

Loading the code for the Love Notes page. To debug this code, open rd4iy.js in Developer Tools.

When I looked into opening the developer tools in my browser I was very confused! :slight_smile:
Thank for all your help

Charlotte
