hi everyone i have the following form that i use to upload files to a web server

<form enctype="multipart/form-data" runat="server">
<tr>
  <td>Select file:</td>
  <td><input id="uplTheFile" type=file runat="server"></td>
</tr>
<tr>
  <td colspan="2">
  <input type=button id="btnUploadTheFile" value="Upload"
                    OnServerClick="btnUploadTheFile_Click" runat="server">
  </td>
</tr>
</form>

this works fine, however i want to call a javascript function when they click the upload button so i can show a hidden layer that say processing.  the problem is i cant get the form to call my javascript i have tried this

<form enctype="multipart/form-data" runat="server" onsubmit="return checkform(this); return false;" >

but it never gets called

can anyone point me in the right direction

thanks
