probably your decimal system is "," not "."
you need to change that in your sytem!
also, next time you should consider giving more information than just this little sentence, how u suppose people will help you?
i mean, really, this only makes it harder for other people, you r the one begging for help, so you should be the one wasting the most time, not the one who is trying to help you because he needs to ask for every single information bit for himself!
