Another small problem,  
With this code:

```
.controller('ListCtrl', function($scope, EventService,$location,$localStorage, $ionicActionSheet, $translate,$stateParams){

$scope.gotoSlide = function(index) { $scope.$broadcast('slideBox.setSlide', index); };

var slidenum = $stateParams.slidenum;
if($stateParams.slidenum>=0){
	$scope.$watch(function(){
		$scope.gotoSlide(slidenum);
	});
}
})

```

I’m getting this error multiplied by the number of pages that I have,

```
