AngularJS Code is working in one codepen, but breaks when moved

I have a range slider that is used to filter products. It works perfectly fine in this codepen, but when i moved it over to my large scaled product, it won't slide AND it breaks my count code on all the <divs> below it. Here is the product's codepen.

I am using Rzajac's range slider which can be found here.

HTML

  <rzslider
        rz-slider-floor="priceSlider.floor"
        rz-slider-ceil="priceSlider.ceil"
        rz-slider-model="priceSlider.min"
        rz-slider-high="priceSlider.max"
        rz-slider-step="{{priceSlider.step}}"></rzslider>

Angular

var app = angular.module('plunker', ['rzModule']);

app.controller('MainCtrl', function($scope) {

  $scope.priceSlider = {
    min: 0,
    max: 20,
    ceil: 20,
    floor: 0,
    step: 1
  };  

$scope.products = [
        {
            name: 'one',
                        height: '00'
                    },
          {
            name: 'two',
                        height: '10'
                    },
          {
            name: 'three',
                        height: '20'
                    }
  ];

  $scope.minFilter = function (p) {
        return p.height >= $scope.priceSlider.min;
    };

   $scope.maxFilter = function (p) {
        return p.height <= $scope.priceSlider.max;
    };
});

The slider is located in the "SIZE" tab, thanks for the help guys!

You're using Angular 1.2.4 in the first Codepen and Angular 1.0.7 in the second. The older Angular is complaining that it doens't understand your directive:

Error: Invalid isolate scope definition for directive rzslider: =?
