Thank you very much !
It's working now :)
After I finished the tutorial I'll try to translate it into Dutch (
which makes it even easier for me and probably other Dutch people .. )
Didn't know what an indentation was ( desperately looking for a
dictionary LOL ).
Will go on with the tutorial .. and if I get stuck again and can;t
figure out what I've done wrong this time I'll be back .. on my way to
becoming a progammer .. in 2010 or so :)

For the correct e-mail address : remove NOSPAM and replace dot with .
