How to stop current sound when going from one slide to another in Flash slideshow

Hi,

I am trying to find a solution to a problem with sound in flash slideshow I’m making.
I am attaching what I have so far…

It will have 31 slides, and almost all slides will have one or more sounds (narrations) in it…

When I play the slideshow and let it go all is good, but when I want to go to next slide before the current slide sound finishes, that sounds keeps on playing and the sound from the next slide also starts so they overlap, when I press space again and go to third slide it’s sound starts as well and now three sounds overlap…

Please help me with this one, I need a quick solution. So I need all the sounds in the current slide to stop when moving on to the next slide.

Thank you very much.
