dropdown list to append :(

Hi,

I have a dropdown list when the user select something from it it should populate the selection to the multi select list.

here's what I have that does not work at all :(

Thanks,
Lulu

$('#SelectSegment').change(function(){	
var selectedGroups = $("#SelectSegment option:selected");
	$.each(selectedGroups, function(index, value) {
		var Companyname = $(value).attr('data-Companyname');
		if ($('#DispSelectedGroupBox option[data-Companyname="' + Companyname + '"]').length > 0)
		{
			alert("Already filtering on " + Companyname);
			}
			else {
		$('#DispSelectedGroupBox').append(value);	
			}
}); 

<SELECT style="WIDTH: 195px" id=SelectSegment name=SelectSegment> <OPTION selected value="" data-Companyname="">Select ...</OPTION> <OPTION value="4;Auto / URMBT" data-Companyname="Auto / URMBT">Auto / URMBT</OPTION> <OPTION value=3;IBU data-Companyname="IBU">IBU</OPTION> <OPTION value="2;Key &amp; Large" data-Companyname="Key &amp; Large">Key &amp; Large</OPTION> <OPTION value="1;Middle &amp; Small" data-Companyname="Middle &amp; Small">Middle &amp; Small</OPTION></SELECT>



       <select name="DispSelectedGroupBox" id="DispSelectedGroupBox" size="180" multiple="multiple" class="SearchBySelect5"  style="height:100px; width:250px;background-color:#f8fafc;"> </select>

jayakrishnabh,

Thank you it works but, I forgot to say that I want to clear what's inside (DispSelectedGroupBox)
before append.

so, I guess I don't need to validate since I am deleting what's in the multi select!!!

I want something like this but my changes doesn't work.

just to delete what's in the multiselect box before the user can append to it.

function changeselection() {
            var selectedtext = $("#SelectSegment").find('option:selected').text();
var multiSelect = $("#DispSelectedGroupBox").find('option:selected').text();

            if (selectedtext != null || selectedtext != undefined || selectedtext != "") {
                var companyname = $('#SelectSegment :selected').val();
                var companytext = $('#SelectSegment :selected').text();
                if (multiSelect != '') {
                		$("#DispSelectedGroupBox option:selected").remove();
                        $('#DispSelectedGroupBox').append('<option value="' + companytext + '" data-companyname="' + companytext + '">' + companytext + '</option>');
            }
        }
