Hello!

I need some help with importing datafile in RayMan. I tried to transform excel file to .txt file as I have to do to compute meteorological data to PET. Problem is that program doesn't compute datas, but it always answers in a way like this:
"Read error from data file!" (Data format? Number of columns?)
I always choose the same number of columns in "Werterdatei" window as in my .txt file. RayMan computes only the first line of datas in a file.

or

"0.3" ist kein gültiger Fließkommawert!.
I usually use "," for decimal point.

I have no idea in what form does a file need to be, that RayMan will be able to compute all datas. Can anyone advise me, how exactly I have to do that?

Thank you for your help!
