Better to show the "Total size of all attachments" in MB instead of showing like "Total size of all attachments: 19007694 "...
Already in the instruction message, it is shown that the Attached files cannot exceed 20 MB in total.
So, if the total size of attachment the user has uploaded is shown in MB, it would be easier for a normal user to understand...
