window doesn't pop up (css, php)
===

I have the following code in my footer.php

    <div id="footer">
    <div id="disclaimer"><a href="#" onclick="popup(0);return(false);" id="closeBTN">close</a> <strong>Disclaimer:</strong><br />
    Testing disclaimer<br />
    
    </div>
    <a href="#" onclick="popup(1);return(false);">Disclaimer</a>
    </div>

and the webpage(let's call it www.mypage.com) shows Disclaimer in the footer, but when I click on it, it doesn't popup any window but instead takes me to the page

    www.mypage.com/#

here is the relevant content of my style.css:

    tr.greyRow td{background-color:#DDD; color:#777}
    
    #disclaimer{display:none; position:fixed; width:500px; height:150px; padding:20px; bottom:0px; right:0px; background-color:#FFF; border:solid 1px #666; color:#333;}
    #footer a#closeBTN{font-weight:bold; float:right; margin:0; color:#9a965d; margin-top:-10px;}

Can someone tell me what I need to fix to get the window to popup and show the contents of disclaimer in the footer.
