The code looks like this
$("th.name ").livequery('click', function() {
var $selected = $(this).children("th.name");
if($selected.is(":hidden")){
console.log($selected);
console.log($selected.find("b").length);
$selected.find("b").removeClass().addClass("subtraction");
$selected.find("a").hide().end
().slideDown("slow", function(){
$selected.find("a").fadeIn();
}, "easeOutCubic");
} else {
$selected.find("b").removeClass().addClass("add");
$selected.find("a").fadeOut(function(){
$selected.slideUp("slow", "easeInQuart");
});
}
};
