[HELP] isDown is undefined

I need some help with my Uni project that I made using Phaser. 

My game is a simple plat former. I have been working on the Player controls, but for some reason I keep getting :"Uncaught TypeError: Cannot read property 'isDown' of undefined"

 

Game.level1 = function (game) {};

//variables

var map;
var layer;

var player;
var controls = {};

var playerSpeed = 150;
var jumpTimer = 0;


Game.level1.prototype = {
    create:function(){
        this.stage.backgroundColor = '#e6ffff';
        
        this.physics.arcade.gravity.y = 1400;
        
        map = this.add.tilemap('map', 32, 32);
        
        map.addTilesetImage('tileset');
        layer = map.createLayer(0);
        layer.resizeWorld();
        map.setCollisionBetween(0,2);
        
        player = this.add.sprite(100,561,'player');
        player.anchor.setTo(0.5,0.5);
        player.animations.add('idle', [0,1], 1, true);
        player.animations.add('jump', [0,2], 1, true);
        player.animations.add('run', [3,4,5,6,7,8], 7, true);
        this.physics.arcade.enable(player);
        this.camera.follow(player);
        player.body.collideWorldBounds = true;
        
        var controls = {
            right : this.input.keyboard.addKey(Phaser.Keyboard.RIGHT),
            left : this.input.keyboard.addKey(Phaser.Keyboard.LEFT),
            up : this.input.keyboard.addKey(Phaser.Keyboard.UP),       
        };

        
    },
    
    update : function () {
        this.physics.arcade.collide(player,layer);
        
        if(controls.up.isDown){
            player.animations.play('jump');
        }
        
        if(controls.right.isDown){
            player.animations.play('run');
            player.scale.setTo(1,1);
            player.body.velocity.x += playerSpeed;
        }
        
        if(controls.left.isDown){
            player.animations.play('run');
            player.scale.setTo(-1,1);
            player.body.velocity.x -= playerSpeed;
        }
        
        if(controls.up.isDown && (player.body.onFloor() || player.body.touching.down) && this.time.now > jumpTimer){
            player.body.velocity.y = -600;
            jumpTimer = this.time.now +750;
        }
       
    }
}

Could anyone tell me what I am doing wrong ?

What Str1ngS says is correct. By saying "var" inside the "create" function, you're creating a local variable instead of adding your object of input keys to the global object you defined at the top of the file. Removing the "var" inside "create" will instead reference the one you created up top.
