Help for the interrupt

Hi,I am a student in ME. Right now I am doing my capstone. We use chipkit uno32 to control our engine. But now I have some problems using arduino.
Here is my code, just simple one.

int rev=0;
int counter=0;
int Ai=3;
int Ao=4;
int Bi=5;
int Bo=6;
int time;
int time1;
int time2;

const int timemin=100  ;
const int timemax=600;
int a;
int b;

void setup(){
  Serial.begin(9600);
  attachInterrupt(0,outercounter,FALLING);
  attachInterrupt(1,intercounter,RISING);

  pinMode(Ai,OUTPUT);
  pinMode(Ao,OUTPUT);
  pinMode(Bi,OUTPUT);
  pinMode(Bo,OUTPUT);
}

void loop(){
  int sensorValue=digitalRead(2);
  Serial.println(sensorValue);

}


void intercounter(){
  counter=0;
  rev++;
  time=millis();

}

void outercounter()
{
  counter=counter+1;
}

When interrupt 1, which is pin 2, rising, it should interrupt the program and reset counter to 0. But now counter only goes up to 1 and back 0. When I Serial print the rev, it looks like how counter it should work.
I also digital read the pin 2. It is good. And also I delete the intercounter, serial print the counter. The counter also works. So I believe it is the code’s problem.

Anyone can help me? Thanks.

Is Int1 pin 3? If so, you're doubling it up with Ai and setting it's mode to OUTPUT.

CHIPKIT UNO32, interrupt 1 is pin 2. I have figured out the problem. The signal should reduce the noise. Thank you also.

Yeah, so have we. THAT"S NOT AN ARDUINO.
