An application is working on one server but doesn't work on another?
<p>I have a new web application. I've setup the application and it's working on one server(xxx) but it's not working on another(yyy). I changed the web.config file(checked throughly and I've changed the connection string and appsettings). </p>

<p>What could be the error?</p>

<p>The login page is working but when I proceed a Javascript error occurs...</p>

<p><strong>(Line: 48 Error: Object doesn't support this property or method)</strong> </p>

<p>Here's the code</p>

<pre><code>function callCompForFileUpload(responseText)
        {
            document.getElementById("btnView").disabled = false;
            var objFolderUpload = document.getElementById("FolderUpload");
            var UploadURL = document.getElementById("HdnFolderUploadURL").value + "?rid=" + responseText;

        // this is error line
            objFolderUpload.ShowForm(UploadURL);
        }
</code></pre>

<p>Thanks saj     </p>
