Weird errors

Slave Handler:

var _interval, _spr, _zones = [B10,B13,B14,B15];
function pwm(zone,brightness, Hz){// 0<brightness<1 Hz>0
  if((typeof _interval) !== "undefined"){
    clearInterval(_interval);
    var i = 0;
    while (_zones[i]){
      _zones[i].reset();
      i++;
    }
    _interval = undefined;
  }
  if(0>brightness<1&&0<Hz){
    _interval = setInterval(function(){
      digitalPulse(_zones[zone], 1, brightness * (1000/Hz));
    }, 1000/Hz);
  }
}

//power burst on the solenoid then bring the power down to reduce amp draw
function ctrlPwm(y){
  _spr=y;
  pwm(_spr,0.9,60);
  setTimeout('pwm(_spr,0.5,40)',500);
}

//read voltage to send back to master controller and turn on requested solenoid
