Arduino serial port error ( special hello to the memberformerlyknownasawol ))

[amin6711]

hi every one specially the memberformerlyknownasawol
my problem is i have recieve 1,1,1,1,1,* from serial port but when i want to send order like 0,0,1,0,1,* the program hangs
i have 5 keys and 5 leds
the keys worked perfectly but the leds that gets on with send order 0,0,0,0,0,* wont work
my friend make this and his leds works perfectly but mine are useless
so did u know what kind of problem may cuz that
i turn off firewall and anti virus
but i dont know what to do
plz help us

const int led1=5;
const int led2=6;
const int led3=7;
