Corpo Theme and FlexSlider

Hey,

I am using the Corpo theme and I would like to adjust the timings of the slider but there are no options to change this. I have tried adding the following into the header.php file but I have had no success. Any help would be greatly appreciated!

<script type="text/javascript" charset="utf-8">
  $(window).load(function() {
    $('.flexslider').flexslider({
			animation: "slide",
			controlsContainer: ".flex-container"
			slideshowSpeed: 7000,           //Integer: Set the speed of the slideshow cycling, in milliseconds
			animationSpeed: 600,            //Integer: Set the speed of animations,
    });
  });
</script>

Cheers
