Running that script you should have seen some error messages. Why don't you post those as well, and be it sheer politeness to give the full picture?

If you want to know if the file named by the contents of the variable named i is a regular file, use:
  if [[ -f "$i" ]]

If you want to know if the string that is the contents of the variable named i is the string, use:
  if [[ "$i" == ""]]

If you want to know if the file named by the contents of the variable named i is a regular file named use:
  if [[ -f "$i" ]] && [[ "$i" == ""]]

Then note that with your loop (if you have three files one of which is named that match the filename matching pattern *.*) you'll echo do nothing once and echo do something twice. Is that really what you want to do?
