Onload Modal - on the edit page...

Hi all,
On my edit page, once loaded the requirment is that a modal dialog box is generated using the script from:
http://www.dynamicdrive.com/dynamicindex8/dhtmlwindow/dhtmlmodal.htm
Nice and neat.
However the dialog box does not load. m(tested externally - not an issue).
I think it is important to mention that on my list page in the java onload event I have the follwong code:
$("tr[id^='gridRow']").hover(function(){

$(this).children().addClass('listrollover');

$(this).css('cursor','hand');

},function(){

$(this).children().removeClass('listrollover');

});

$("a[id^='editLink']").bind('click', function() {

return false;

});

$("tr[id^='gridRow']").click(function(e){

$(this).find("a[id^='editLink']").trigger('click');

$(this).css('cursor','hand');

});
I am assuming there could be a conflict and to this end I have played around with various code without success.
Any ideas very much welcome....
TIA
