How to publish Animation in html 5 with flash CC

Hi

I am using Flash CC trial version and want to export AS3 animations in HTML5. I have gone through this tutorial :

https://tv.adobe.com/watch/learn-flash-professional-cc/export-the-project-for-the-web-ipad -and-more/

and tried in Flash CC was shown in the tutorial, but I am not able to export even a small animation with a box moving from one side to another. Only static flash work gets exported in canvas but even simple button or simplest animation is difficult to export into HTML5.

I don't know where I am going wrong.

I created a simple animation of a box going from left to right in AS3 with classic tween and used convert AS3 to HTML5 canvas option and published it to (dot)js format.But animations are not working for me, it shows a blank html page. And i always get errors in output saying Ease CS animation starts from frame 0 where as flash from frame 1.

Please help.
