SQL Injection Atack on Select Statement
I'm trying to accomplish a SQL injection using Tamper Data add-on on Firefox. I was provided a web site prepared for this purpose and what I need to do is to fill the username and password fields with appropriate strings to be logged in.

First of all, I double checked that "magic quotes gpc" is Off. After that, I write the following line both to the user name and password;

    test' or '1=1
But still, I cannot log-in to the system. Any idea why is that happening?
