so here
if ($("#banner-ad-top").length > 0) {
var b2 = setInterval(function () {
$.ajax({
url: window.SnitzVars.baseUrl + "Ad/TopBanner",
cache: false,
dataType: "html",
success: function (data) {
$("#banner-ad-top").html(data);
//$('#featured-img').css('visibility', 'visible').hide().fadeIn(2000);
}
});
}, 30000);
changing the numbers 2000 or 3000 don't seem to make a difference
