Help: ordered data set

I’m creating a timeline to stop a movieclip at specific times.

Using setInterval I’d like to use an if statement to pause my movieclip at each of the times indicated by variableTimes:

variableTimes = [15, 20, 25];
if(myTimer=variableTimes){
myMovie.stop();

However, I can’t seem to figure out how to give variableTimes three independent variables. Help?
