Sorry : my mistake. Change the line

bool StateB2 = digitalRead(PIN_BUTTON1);

to
bool StateB2 = digitalRead(PIN_BUTTON2);(PIN_BUTTON2 instead of PIN_BUTTON1).
It should be OK now (fingers crossed)

It all works perfect. Thanks again. Got a quick question though would it be hard to modify this code to allow me to set the individual led's to different colors?
