(Flash 8) Help! With random Pause Time!

Hi, I´ve been trying to make a code that works by pausing(delaying) for a random amount of time between commands. This code would be on last frame in a movieclip, so the movieclip would be delayed before going back to the start.

Example for the last frame:

stop();

//here would be some sort of a delay code…?

gotoAndPlay(“start”);

Can someone help me:)?
