simple laser sensor help needed

http://forum.allaboutcircuits.com – I would like to ask a fast question, I don't belive it is very complex, I made an extremely simple circuit, to use a photoresistor as a laser detector, this might be the wrong place to ask, but im giving it a shot, the "laser" im using is just a 3 dollar wal-mart laser pointer, I took a photoresistor, out of a grab bag from radio shack, and a blue LED, and a variable resistor, I put the variable resistor in line with the photoresistor, then to the positive side of the led, and the other side of the LED to ground, its using +12 volts, only because im using a +12 volt adapter, that was (Embedded)
