Need a little help at JS.

Hi guys, there's something at which i need help... <body> <div id="Chandler"> 8</div> </body> <script> var Joey = document.getElementById ("Chandler"); var op=Joey.innerHTML; Joey.innerHTML=op+5; </script> Now, instead of adding 8 and 5 and giving the result 13, the code gives 85. Any solution by which I can add 8 or any number with 5? Thanks for answering.

var op = parseInt(Joey.innerHTML, 10); "innerHTML" returns text (a string), so the 5 you added was converted to text, too. Converting op to a number like I did will work :)
