How to set default tab for initial load

Currently this webpage opens to the tab, "Freebies & Extras." I want it to open to the first tab, "Commonwealth & Council." I believe, by default, it will open to the first tab. I tried to locate where it is telling the browser to open it on the third tab but couldn't find it.

Solution

You need to set the active to 0 in the code

$(document).ready(function() {
    $('div#Panels').tabs({
    active: 2,
    collapsible: false,
    activate: function(event, ui) {...

UPDATE

When you click the tab 0, then the page runs this code:

$('#carousel').flexslider({
   animation: "slide",
   controlNav: false,
   animationLoop: true,
   slideshow: false,
   itemWidth: 80,
   itemMargin: 5,
   asNavFor: '#slider'
});

$('#slider').flexslider({
   animation: "slide",
   controlNav: false,
   animationLoop: true,
   slideshow: false,
   sync: "#carousel"
});

//-----------------
$(window).resize();
//-----------------

Since you are not clicking this tab to start, this code is not running when the tab opens. You need to run the code by yourself. I suggest create a function and call it right after defining the tabs.

The full script would be (maybe something is misplaced, because I haven't run it):

function ClickedTab(carousel, slider){
   $(carousel).flexslider({
      animation: "slide",
      controlNav: false,
      animationLoop: true,
      slideshow: false,
      itemWidth: 80,
      itemMargin: 5,
      asNavFor: slider
   });

   $(slider).flexslider({
      animation: "slide",
      controlNav: false,
      animationLoop: true,
      slideshow: false,
      sync: carousel
   });

   //-----------------
   $(window).resize();
   //-----------------
}

$(document).ready(function() {
    $('div#Panels').tabs({
        active: 0,
        collapsible: false,
        activate: function(event, ui) {
          switch (ui.newPanel.index()) {
           case 0:
              ClickedTab("#carousel", "#slider"); break;
           case 1:
              ClickedTab("#carousel2","#slider2"); break;
          }
        }
    });
    ClickedTab("#carousel", "#slider")
})
