javascript - Button not calling a function -

-

i creating simple array counter , sorter school , have encountered problem count button calling count() function. here's code.

<!doctype html> <html>   <head>     <script language=javascript>       var products = ["printer","tablet","router","keyboard","headset"];         function sort() {         products.tostring()         document.getelementbyid("result").innerhtml = "unsorted array = " + products;         products.sort();         products.tostring();         document.getelementbyid("result2").innerhtml = "sorted array = " + products;       }        function count() {         document.getelementbyid("count").innerhtml = "the amount of items in array is: " + fruit.length;       }     </script>     <title>task 2</title>   </head>    <body>     <input type="button" name="butt1" value="sort!" onclick="sort()"/>     <input type="button" name="butt2" value="count!" onclick="count()"/>        <p id="result"></p>     <p id="result2"></p>     <p id="count"></p>   </body> </html>

that because fruit not visible count function

i guess want use products here

function count() {      document.getelementbyid("count").innerhtml = "the amount of items in array is: " + products.length; }

or if want use fruit, need declare , initialize globally
