javascript - Functionality Issue using the '.animate()' Function -


i working through jquery curriculum on codecademy , particular assignment involves using switch function in conjunction multiple instances of '.animate()' function. 'img' in question our favorite italian plumber move left. when run code error returned " oops, try again. looks image doesn't move right when press 'right'." 

$(document).ready(function() {     $(document).keydown(function(key) {         switch(parseint(key.which,10)) {             // left arrow key pressed             case 37:                 $('img').animate({left: "-=10px"}, 'fast');                 break;             // arrow pressed             case 38:                 $('img').animate({up: "-=10px"}, 'fast');                 break;             // right arrow pressed             case 39:             $('img').animate({right: "-=10px"}, 'fast');                 break;             // down arrow pressed             case 40:                 $('img').animate({down: "-=10px"}, 'fast');                 break;         }     }); });  

$(document).ready(function () {     $(document).keydown(function (key) {         switch (parseint(key.which, 10)) {             // left arrow key pressed             case 37:                 $('img').animate({left: "-=10px"}, 'fast');                 break;                 // arrow pressed             case 38:                 $('img').animate({top: "-=10px"}, 'fast');                 break;                 // right arrow pressed             case 39:                 $('img').animate({left: "+=10px"}, 'fast');                 break;                 // down array pressed             case 40:                 $('img').animate({top: "+=10px"}, 'fast');                 break;         }     }); });
