AC Dimmer time control

With this code the timer works oke.
After i made the last part of the code active the timer is not working oke anymore.

/* 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);
  }
  */

So it looks that

attachInterrupt(0, zero_crosss_int, RISING); // Choose the zero cross interrupt # from the table above

has influence on the timer.
