hi,  
this might be an easy question but i have not found the answer.

i want a MC to move vertically upwards and then stop. i have the code below but this tweens downwards. i tried changing the -30 value but it doesn’t seem to change the starting point. any tips please??

import mx.transitions.Tween; import mx.transitions.easing.\*; var xPosT:Tween = new Tween(kText, “\_y”, Bounce.easeOut, -30, 56, 3, true);}; xPosT.onMotionFinished = function() {};
