Ubuntu :: SH Script - Print Remotely Through Dropbox

What I am trying to do is print remotely through dropbox. so I am having a sh script check a folder called PrintQueue in my Dropbox and whatever file is in there it prints

Here is the script
Code:
#!/bin/bash
export PrintQueue="/root/Dropbox/PrintQueue";
IFS=$'
'for PrintFile in $(/bin/ls -1 ${PrintQueue}) do
lpr -r ${PrintQueue}/${PrintFile};
done

Here is what the terminal says:
Code:
christoph@christoph-desktop:~$ sh dropprint.sh
dropprint.sh: 5: Syntax error: word unexpected (expecting "do")
