What to put as swf file in TableTools

问题

I'm a very new programmer with no experience with tabletools or swf paths whatsoever. I'm trying to implement Table Tools to print/export/etc but so far only print is working for me. Most solutions have said that means the swf path is incorrect. But I have no idea what to put as my swf path. Could anybody please help? Sorry for such a basic question. :(

Here are my plugins and script for dataTables:

        });

    });
