Keep up the excellent work! I have a question on this tutorial about the expressions?
Do you know why I keep getting this error (( " After Effects warning: Expected:: Expression disabled )).........:(? This only happens when send it to my friends. It happens all the time...:( I really like this Expression a lot, but I guess it wont work in other computers? Every time I opened in my computer it works fine. Can you please help me why it keeps giving me the error. Thanks again bud, you are a great teacher!

Marty

Thanks for your feedback Marty. This

Thanks for your feedback Marty. This error sometimes happens when you open a project that has expressions and was created on a different platform (Mac vs. PC). I'm not sure why is that. Usually when you re-enable the expressions it fixes itself, then you should be good to go. Maybe it's worth to copy this question to the AE expressions forum as well: http://forums.creativecow.net/adobe_after_effects_expressions

Thanks a lot!

Hi Eran!

After this tutorial, I must to say in public: I AM SORRY! Why???
Because since the first time I heard your english accent, I skipped a lot of your tutorials just because of it. And must to confess that your last words in this tutorial touched me deeply! I felt your charisma and love for family and friends... this made me think about my behavior in real life. I'm too far from them, spending almost 14 or 15 hours in front of my pc.
So, I hope you understand me, alright?

Greetings from Brazil!!!
