AC Dimmer time control

If i use the code below nothing is happening.

The timealarm code works fine but if i insert the dimmer code it doesn't work any more.
I think i make a mistake with logical order.

#include <Console.h>
#include <TimeLib.h>
#include <TimeAlarms.h>

AlarmId id;

int AC_LOAD1 = 10; // Output to Opto Triac pin
int AC_LOAD2 = 11; // Output to Opto Triac pin
int dimming1 = 128; // Dimming level (0-128) 0 = ON, 128 = OFF
int dimming2 = 128; // Dimming level (0-128) 0 = ON, 128 = OFF

void setup() {
 
  // Initialize Console and wait for port to open:
  Bridge.begin();
  Console.begin();
  
  setTime(8,29,0,1,1,11); // set time to Saturday 8:29:00am Jan 1 2011

  // create the alarms, to trigger at specific times
  Alarm.alarmRepeat(8,30,0, LightOn);  // 8:30am every day
  Alarm.alarmRepeat(8,35,0, LightOff);  // 8:35am every day
  

  pinMode(AC_LOAD1, OUTPUT); // Set the AC Load as output
  pinMode(AC_LOAD2, OUTPUT); // Set the AC Load as output
  
  attachInterrupt(0, zero_crosss_int, RISING); // Choose the zero cross interrupt # from the table above
}

void loop() {
  digitalClockDisplay();
  Alarm.delay(100); // wait one second between clock display
}

// functions to be called when an alarm triggers:
void LightOn() {
  dimming1 = 0; //Full = 0
  dimming2 = 0; //Full = 0
}

void LightOff() {
  dimming1 = 128; //Off = 128
  dimming2 = 128; //Off = 128
}

void digitalClockDisplay() {
  // digital clock display of the time
  //Console.print(hour());
  printDigits(minute());
  printDigits(second());
  //Console.println();
}

void printDigits(int digits) {
  //Console.print(":");
  if (digits < 10)
    Console.print('0');
  //Console.print(digits);
}

void zero_crosss_int() // function to be fired at the zero crossing to dim the light
{
// Firing angle calculation :: 50Hz-> 10ms (1/2 Cycle)
// (10000us - 10us) / 128 = 75 (Approx)
int dimtime1 = (75*dimming1);
int dimtime2 = (75*dimming2);

if ( dimtime1 > dimtime2)
   { delayMicroseconds(dimtime2);
     digitalWrite(AC_LOAD2, HIGH);
     delayMicroseconds(10);
     digitalWrite(AC_LOAD2, LOW);

     delayMicroseconds( dimtime1 - dimtime2);
     digitalWrite(AC_LOAD1, HIGH);
     delayMicroseconds(10);
     digitalWrite(AC_LOAD1, LOW);
    }
    else
    { delayMicroseconds(dimtime1);
      digitalWrite(AC_LOAD1, HIGH);
      delayMicroseconds(10);
      digitalWrite(AC_LOAD1, LOW);

      delayMicroseconds( dimtime2 - dimtime1);
      digitalWrite(AC_LOAD2, HIGH);
      delayMicroseconds(10);
      digitalWrite(AC_LOAD2, LOW);
    }
