I was thinking about having two counters, one that would stop after 10 minutes and one that would continue.. The code i use is:

onClipEvent (enterFrame) {
currentTime = getTimer();
elapsedTime = Math.round((currentTime - 30000 - startTime)/1000);
mingone = elapsedTime;
radiated = elapsedTime + "0%";

where "mingone" is the variable that is gonna continue and radiated is the one that should stop (at 100%..)

any good suggestions on this issue?
(it dont have to be multiple counters, just a way getting it to work..)
