Stupid IE won't show UI Dialog

Stupid IE won't show UI Dialog


I took the demo from the jQuery UI website. Changed a few things (see
below). Works great with Safari and FF, but IE (6.0 and 7.0) give me
an error: "Expected identifier, string or number" and I just don't
understand why.
I am using the latest jQuery and UI scripts (downloaded them
yesterday), uncompressed.
$(function() {
        $("#dialog").dialog({
            bgiframe: true,
            resizable: false,
            height:200,
            modal: true,
            overlay: {
                backgroundColor: '#000',
                opacity: 0.5
            },
            autoOpen: false,
            buttons: {
                'Simple': function() {
                    document.getElementById(changeID).innerHTML="Simple";
                    $(this).dialog('close');
                },
                'Composé': function() {
                    document.getElementById(changeID).innerHTML="Composé";
                    $(this).dialog('close');
                },
            } ******** Gives me an error on this line
        });
    });
