basic web 16

i suck at sql injection. i'm really unfamiliar with SQL as compared to anything else but i've read up on it as much as i could and so far nothing seems to work. I've been tryin to inject into the filed with ' OR 'x'='x to make the statement always true but that didn't work. i can't even get this thing to give me an error. any help?

replace x with 1

yeah i tried that too. Should i be injecting into the field? i'm assuming so because that's where the SQL gets the input from right?

im shit at SQL injection aswel but all u gotta do is read thru the articles thts wot i done nd i passed it

dude change your sig, its massive and shit
