TypeError: Error #1009

1

Hello all,

I have a portfolio website and found a nice series of code for a slideshow. When I placed in my script I received a 1009 error and have failed to find a fix since it shows no compiler error…

TypeError: Error #1009: Cannot access a property or method of a null object reference.

my line of code…

//Flash- get code thats going to make the tween work…

// check which container is currently in the front and

// hide the old slide

// create a new loader for the slide
slideLoader = new Loader();
// add event listener when slide is loaded
slideLoader.contentLoaderInfo.addEventListener(Event.COMPLETE, fadeSlideIn);
// add event listener for the progress

// load the next slide
slideLoader.load(new URLRequest(xmlSlideshow..image[intCurrentSlide].@src));

// show description of the next slide

// show current slide and total slides

}

// init slideshow
init();

Any help would be appreciated!!
