I have a problem using JavaScript that seems to function properly in IE but not in Mozilla Firefox..

Following is a simple example for that kind of JavaScript code:

XML

<head>
    <title>Helo World</title>
        <script type='text/javascript'>
            function ShowSelection() {
        try{
            alert('Your selection is ' + SelectColor.value);
            BodyContent.style.backgroundColor = SelectColor.value;
            }
            catch(e){alert('An error has occurred: '+e.message)}
    }
    </script>
</head>
<body>
    <div id="BodyContent">

        <hr />
         Select a color theme:
        <select id="SelectColor">
            <option value="white">White</option>
            <option value="yellow">Yellow</option>
            <option value="silver">Silver</option>
        </select>
        <input id="SelectionBTN" type="button" value="Select" onclick="ShowSelection()"  />
     br mode="hold" />  </div>
</body>
</html>

You can try this and you can see EVERYTHING WORKS FINE WITH IE, but NOT with Mozilla Firefox. In Firefox it gives an error that saying "function is not defined". Why? How to fix it??

Which version of firebox it is?. if it is older version then you may need to use the document.getElementById method

Since you are having a problem with FF, are you familier with firebug[^]? If not why not get it and debug it yourself. It is a great javascript debugging tool, I am sure you will like it.
