XML slideshow autoplay w/ buttons

Hey all,
I am trying to get the XML photo gallery slideshow to autoplay. I have code that pulls in from an XML file that does autoplay but I can’t for the life of me figure out how to include the buttons (next image and previous image) in my AS. So I tried starting with the code that has the buttons and trying to get it to autoplay but no success. I basically want it to work just like this
Any pointers?

Here are my files.

Thanks a ton!
PS: I’m still in Flash 8.
