Swapna, you are missing the following info:
- The error you are seeing when trying to use the File Upload or the behavior you are seeing.
- Paste the HTML around the file widget and the XPath you are using to target it.
- Is the PDF that you uploaded, accessible in the portal? meaning, when you go to File Uploads in Subject7, are you able to download the file from the direct link there?
- Is any other PDF file work or is it just this one particular PDF that is not working? Please try other PDF documents to make sure.
- Have you tried to re-upload the PDF file, maybe it wasn't uploaded correctly the first time?
