Timer Controlled Events?

ok, for a college assignment i’ve been set the task of creating a flash game, i’ve made a pretty good game so far, a top down shooter, however, the game doesn’t have much to it and in all honesty it’s a bit hard, so i’ve decided to make the game about survival and not about killing, with this in mind can someone help me witha timer controlled event. i’ve searched the net and the few tutorials i have found either dont apply or hurt my head. Basically i’m looking for the coding which would tell my game after 30 seconds goto next scene. i realise this might seem a stupid question to some of you, but this isn’t my forte.

any help would be insanely greatfully appreciated
