I am writting a script in flash that I need to know the movie frame rate. (i know i can look it up in the properties bar) but i want the script to be portable from one movie to another no matter what the frame rate is set to.

Does anyone know a function that i may use?

Thanks for your help, oh and btw first post... Hello World!

// create interval object
intervalObj = new Object();
intCount = 0;

// create interval function
intervalObj.interval = function() {
/// if counter < 100 then a second has not yet passed so move the movieclip
if (intCount < 100){
intCount++;
tweenMC._x++;
} else {
// stop the interval function when time expires
clearInterval( intervalID );
}
}
// start interval with ID "intervalID" (i.e. execute above function every 10 milliseconds)
intervalID = setInterval( intervalObj, "interval", 10);

i solved it ^^^^ code above

Not sure if this is relavent, but your code evaluates an absolute value (time) where the frame rate on a Flash movie rarely contstant, and rarely what is in the frame rate box. I believe.
