Smoothing actionscript tween: need help

ok… i am trying to emulate the thumbnail scroll feature of this site http://www.carldekeyzer.com/… it is at the bottom of the screen of every gallery…

and this is what i have done in the attached file…

ok here goes… hope u guys understand wat i trying to say… :sleep:
i want to smoothen the movement of the thumbnails animation… meaning if the first thumbnail moves a little or half way of its tween but have not reached its destined position, the next thumbnail on the left or right will begin to tween… same goes to the rest of the thumbs… something like overlapping animation

i gone thru the fading grid tutorial and understand the logic behind the smoothing code and thought it might work for my case but it doesn’t seems to work… using the additional “continue” function which i tried…

i just need to tweak this part and i’m on my way to the next part of my project… any suggestions is greatly appreciated… tks
