PortableApps.com Installer script won't compile correctly

I've been trying to make an installer for the app I just put together. After editing the script a bit and making sure I have the files it wants, it still won't compile properly because of an error with uninstall functions that I can't find anywhere in the script. Anyone have any ideas about it?

Note: uninstall functions must begin with "un.", and install functions must not
