Timers and Sounds?!

Hey guys,

I REALLY need some help. I will admit I pretty much suck at flash.

Heres what I’m trying to do.

drop down box with values 5, 10, 30 (theses will be minutes)

then after selecting a time from the drop down box I need to play a sound every X amount of minutes where X is the selected value.

so if I pick 5 it will play a sound every 5 mins.

Thanks!
