/*

AS OF 7/21/09 THIS IS HOW IT WORKS - JS
two divs go into the global master

 <div id="dropinboxv2cover">
        <div id="dropinboxv2">
            this is overwritten with an error message            
        </div>
    </div>
    
then a hidden field goes into the global master

<asp:HiddenField ID="hf_ErrorMessage" runat="server" />

finally a javascript snippet is added to the global master at the very bottom of the page to trigger it to be fired
evertime the page is loaded

 <script>CheckErrors();</script>
 
 There are images that are displayed Exclamation64.png
 
 AND one CSS file 3c_ErrorBox.css
