Hey,
Firstly, I recommend checking out the article of " How to Use the Upload Button with Code ":
Moreover, I recommend the following steps:
- Add a submit changes button and create an onClick event.
- Set the field value with the new image URL .
- Save the changes.
- Refresh the dataset.
Should the issue persists, please send us a video of the issue using screencast so that we can better understand. Moreover, please send us the site URL.
Have a good day,
Tal.
