Caurina tweener: how to make a movieclip begin a tween at a certian frame?

1

(sorry if i accidently posted this twice)

I am using the caurina tweener and i know that by default the tween will begin to tween at frame 1 and tween till _frame:number

how can i make a tween start at a certian frame? such as make thetest tween at frame 25 to 50

here is the code



import caurina.transitions.*;
import caurina.transitions.properties.DisplayShortcuts;
DisplayShortcuts.init();


thebutton.addEventListener (MouseEvent.ROLL_OVER, thebutton_ROLLOVER);




function thebutton_ROLLOVER (e:MouseEvent) :void
{
    Tweener.addTween (theicon, {_frame:27, time:0.5, transition:"linear" });
    Tweener.addTween (thetest, {_frame:50, time:0.5, transition:"linear"});
}


thebutton.addEventListener (MouseEvent.ROLL_OUT , thebutton_ROLLOUT);


function thebutton_ROLLOUT (e:MouseEvent) :void
{
    Tweener.addTween (theicon, {_frame:0, time:0.5, transition:"linear"});
    Tweener.addTween (thetest, {_frame:0, time:0.5, transition:"linear"});
}
