Move object to position and stop


Ok… this should be pretty simple for most, but I would like an explanation more than just a quick code fix. I put all the script together for this object, here is the fla. What I want to do is move it up to the y position as it does, but I need the object to move faster and stop there. Since I have given most of script in the main movie, I don’t know how to write the script for the button release. All I can get it to do is crawl up with targety=100; but I still have the problem with the mouse follow once my button is pressed. I just want it to go up and stay.

Thanks in advance for the help.
