[Flash CS3] AS 2 - Current Frame + n frames

Hello,
In my flash file I would like to be able to click a button and jump a head by “n” frames from the current frame (as opposed to jumping to a predetermined frame).

Something similar to (but obviously a bit more complicated than)
gotoAndPlay(currentframe + n);

I would like to do this because there are animations going on that need to resume from the same place. So in my case I would jump ahead 273 frames from the current frame so that there is not skip in the animation.

How would I go about this?

Thanks,
-Ian
