Answer 1

you have many errors in that code

1. Extra ; after { (in both functions (before you updated)
2. documente instead of document (before you updated)
3. You call an undefined function UploadFileChange (you called it UploadFielChange) (before you updated)
4. No quotes inside getElementById()

and as a sidenote it’s useless to close a script block and then reopen another one on next line. Both the functions can be enclosed in the same script block
