Submitting my video via USB stick

After many many tried and failed attempts to upload my video up onto my blog, I have diecided that i wil be submitting my composition via USB stick. 

There will be more than one version on there, just as proof that my many rendering attempts have failed to include the sound. I hope that, based on my previous posts on showing my attempts, this wont be a problem. 

Struggling with sound!!

I have managed to animate my images in After Effects, although no matter what I try I cant seem to get the sound working properly. I have followed numerous tutorials on how to export and render a composition with audio, and no matter what I try I cant seem to get it working. a

I have taken some screen shots to allow my problem to be shown more clearly. 

I have highlighted the parts of the screen shot where it is evident I have included my assigned audio clip, The Third Man Theme. 

Here are some links to some of the tutorials I followed, and still no luck.
