The below code below was taken online and was written for the Arduino uno,Uno. I know C++ however I am a beginner with Arduino so I don't understand this compatibility issue or how to fix it. I am very thankful for any help. Here is part of the code - the variable declarations: (I can upload the entire code if that would be more helpful).
ISR(PCINT0_vect) {
current_time = micros();
//Channel 1=========================================

if(last_channel_1 == 0){ { //Input 8 changed from 0 to 1.
last_channel_1 = 1; //Remember current input state.
timer_1 = current_time; //Set timer_1 to current_time.
}
}
else if(last_channel_1 == 1){ { //Input 8 is not high and changed from 1 to 0.
last_channel_1 = 0; //Remember current input state.
receiver_input[1] = current_time - timer_1; //Channel 1 is current_time - timer_1.
}
//Channel 2=========================================
if(PINB & B00000010 ){ { //Is input 9 high?
if(last_channel_2 == 0){ { //Input 9 changed from 0 to 1.

}
//Channel 3=========================================
