ASP + CKFinder + JavaScript

Evening,

I'm currently developing a .net project in which i want to open ckfinder through javascript code.

Here's my javascript functions:

    <script type="text/javascript">
        function BrowseServer() {
            var finder = new CKFinder();
            finder.BasePath = '/ckfinder/';  
            finder.SelectFunction = SetFileField;
            document.getElementById('ckfinder_inner').style.display = '';
            document.getElementById('ckfinder_inner').innerHTML = finder.CreateHtml();
        }
        function SetFileField(fileUrl) {
            document.getElementById('thumb_path').value = fileUrl;
            document.getElementById('ckfinder_inner').style.display = 'none';
        }

In HTML i have the following:

               <input id="thumb_path" type="text" />
                <input id="Button1" type="button" value="button" onclick="BrowseServer();" />

Whenever i click the button.. Nothing happens. Any help with this? Thank you very much.
