Hi,
i played with this. It was my fault sorry if i caused extra work. The explanation what was the exact Problem might be interesting for people from Europe (like me i'm from germany) importing this into Excel.
The Setting here have to be like this.

The "decimal separator" (that's how its called in German Version translated to english) has to be "."
In my defendance i have to say it wasn't logic for me that this could have caused this error since, and that was now what was the real trick: The combination of the "1000's separtor setting" and the "decimal- separator" led to the "weird" effect that all numbers below 1 where shown correctly but all number beyond 1 not. finally realising this led me to the point that i thought: "Hm O.K. it shouldn't be somethign with the decimal seperator since the numbers in the beginning are right, but let's check it again.
Sorry for wasting your time...
Greetings.
