HELP: Simple Motion Tween is not working

Hello guys,

I badly needed your help. I got confused with something I used to be good at. I just can’t figure out why a simple movieclip is not performing as expected.

Here’s what happened:

In my MAIN SCREEN, I placed a a movieclip and named it “mainnav_mc” and on my ACTIONS layer, I placed a script on the frame that will eventually play the movie “mainnav_mc”. This is the script:

mainnav_mc.gotoAndPlay(“show”);

The clip is suppose to fade-in but it seems that MOTION TWEEN is not working. I tried to create a test MC and still it’s not working. I am really confused on something so simple yet so frustrating.

Please help, I would really appreciate your expertise on this matter. I just can’t crack it anymore :frowning: Please download the FLA file I attached.

Best regards,
Nalla
