hello in the documentation it says:
" 1. In your app, add a Storage Bucket and a Data Service entity that has file fields.
2. Add a File Uploader and a Button control.
3. Create a variable of type AppsFile and name it "SB_file_var’. Use this variable to store the file downloaded from the storage bucket.
4. Add the Upload file to Storage Bucket rule to the Clicked on event of the button control.
In the File to upload field, reference the file uploaded through the File Uploader control, as follows:
MainPage.FileUploader.Value
I’m not sure how this MainPage.FileUploader.Value should be used, please help.
also please advise how the File Name (with extension) should be entered in the downloadFilefromStorageBucket.
