Simply preloader problems

[oarlus]

Hi

I tried to create this preloader and test it but it seems not to work. I saw this tutorial, i tried to do it but unfortunately it doesn't work for me.
Can someone help me throught this one.
I want to do it the easiest way possible. just :
a loading bar ( white line )
a background bar ( a blu background bigger line )
a AS ( which i am not able )

i sent the file in attachments please look at the AS inside the symbol, an tell me where i'm wrong

thanks so much in advance
