capture mode to a frequency counter

THIS MY CODE:

unsigned int buffer[20];
unsigned char i=0;
void main(void)
{
  volatile unsigned int i;

  WDTCTL = WDTPW + WDTHOLD;                 // Stop WDT
  if (CALBC1_1MHZ ==0xFF || CALDCO_1MHZ == 0xFF)                                    
  {
    while(1);                               // If calibration constants erased
                                            // do not load, trap CPU!!
  }
  BCSCTL1 = CALBC1_1MHZ;                    // Set DCO to 1MHz
  DCOCTL = CALDCO_1MHZ;
  InitializeLcm();
  P1SEL |= BIT1;                            // P1.1 CCI0A
  TACTL = TASSEL_2 + MC_2 + ID_3;                  // SMCLK, contmode
  TACCTL0 = CM_1+CCIS_0+SCS+CAP+CCIE;
 
  CCTL1 = CCIE;            // Habilita interrupção do Timer A...
  CCR1  = 31250;           // ... a cada 31.250 ciclos ...
 
   _BIS_SR(LPM0_bits + GIE);                 // Enter LPM0 w/ interrupt
 
}

#pragma vector=TIMERA1_VECTOR
__interrupt void TimerA1(void)
{
    LcmSetCursorPosition(1,0);
    printDecimal(i);
    i = 0;
    CCR1 += 31250;
}
#pragma vector=TIMERA0_VECTOR
__interrupt void TimerA0(void)
{
 
buffer[i++] = TACCR0;
    if (i>10)
    __no_operation();                       // PLACE BREAKPOINT HERE
                                            // VIEW 'BUFFER' VARIABLE
}

----------------------

I am trying to one frequency counter, in this code, the counter read the value of i, set = 0 and restart the count of pulses

but don´t work... :(
