Need Help Tweening Frames

Hi, I am using the Tweener class from caurina.transitions and I trying to tween the frames of a movie clip. This is what I have and it is not working and returning an error. This is the Tweener code:

Tweener.addTween(ticket, {_frame:18, time:0.5, transition:"linear"});

The error is this:

## [Tweener] Error: The property '_frame' doesn't seem to be a normal object property of [object ticket_1] or a registered special property.

Now what do I have to use instead of _frame?

Thanks in advance.

// in order to use the tweener class
import caurina.transitions.Tweener;

// in order to use the _frame special propery
import caurina.transitions.properties.DisplayShortcuts;
DisplayShortcuts.init();

It worked, thank you very much.
