I have two problems with my code when I want to use Manipulate.
First when I change the value of the slider sometimes I have an error message.
Secondly when I change the date with the PopupMenu nothing occurs.
And why I need to do after that if I want to use it with CDF player ?
If someone can help me, I use mathematica 8 and I hope all is clear.
Thanks for your answers
