<script> var t= setInterval(gunned,500); var ini = 0; //our box element var bullet = document.getElementById("bullet"); function gunned() { ini += 1; bullet.style.left = ini+"px"; } </script> ^Post your JS script at the bottom of your HTML <body>. Basically, it's loading your script before it loads the HTML, so the element with the ID "bullet" doesn't exist at the time that JS checks. If you put it at the bottom of your HTML, it'll load the HTML first before it loads your script, thus the element "bullet" will exist at that time. Hope that helps.
