We need a little more information perhaps - what are the other inputs doing?  You realize that for the motor to turn you need to drive one wire high and the other low - so the two inputs for that motor need to be opposite logic levels to produce motion.

i fixed it really easy. i connected 10k resistor from input pins on l293 to ground. i also connected input pins to arduino and it works.
