It's so silly!!!!! we know where the mistake is coming from: We, as European are using a comma instead of dot for writing a decimal value! Now it's clear, why you never got this mistake! F.e. just type -0.043 instead of -0,043 In our case it's working now! We are going to send this message to all the other fellows in the 'outlands' Greetings Matthias PS: We'll get the $50???
