in reply to Howto Include JavaScript to CGI.pm Script

It is now working fine for me. I suggest to add onLoad JavaScript handler which will finish checkbox initialization after page load. Example untested code: 
<script type="text/javascript">//<![CDATA[
function init() {
  twofastest = document.getElementById('twofastest');
  if ( twofastest ) {
    if ( twofastest.checked ) {
      twofastestClick();
    } else {
      checkBoxClick();
    }
  }
}
window.onload = init;
//]]></script>

    Hi, Do the line code: " twofastest = document.getElementById('twofastest'); if ( twofastest )" will retrieve the elementid "twofastest" while window load the page ? Because in my code after i add condition "if", it works. Before it always throw eror element id is null because it was calling on load page

      Jesus please let me give you some advice to avoid all future bugs of this nature, that whole object oriented style of writing HTML code makes me cry just write the actual code out and you will see that every single unique checkbox has an onClick() that you can add to it, javascript and HTML mesh like candy, javascript and OOP style generated HTML mesh like hotdogs and cold rice.
