The answer should look like that: http://i.imgur.com/AyZ7uYV.png

I repeat: in this specific challenge - You're NOT supposed to pull the version\db name. THIS IS BLIND SQL INJECTION
You're supposed to pull information out of a table just by guessing the table name & its columns
(*note: using information_schema db is not allowed)...
