Error when I test movie. Flash file (Mobile)

programming flash
1

I create a mini game for my mobile phone ,but when I test movie I get this error when I create a Flash File (Mobile).
"

You must export your movie as  Flash 5 to use this action

" . This is a “generic” error every time when I try to compile. I wrote a simple function to “test” the error and i get again with :

function hello(){
  //ham
}

My game works fine when I create a simple flash file but in Flash File mobile , doesn’t work …

I think I do smth wrong , but I don’t know what . I use fl CS3
Thanks in advance :egg:
