Reversing frames on button release

Thanks a lot, but I tried your code and it didn’t work for me (and your code was wayyyyyy to confusing with the dutch comments, lol, thanks though). I’ll link to an FLA since the limit on this board is 75k and this one is 112k.

On frame 45 there is an invis button (on top of the work text, instance name workBack) that on release needs to play the frames back until it reaches frame 15 at which point it stops. This is all in the work movieclip (on the bottom under the bottom bar). Many thanks to anyone who can help me as i’ve tried numerous amounts of code with nothing resulting the way i want it to work.
