Creating a sfc data file

Hi,
I am trying to create/populate a surface data file. I have used sfcfil to create the empty .gem file, and I have an ascii text file with the station data. However, when I run sfedit I get the following errors: 

[SFEDIT -8]  Parameter HOUR is not in the data set.
[SFEDIT -8]  Parameter DRCT is not in the data set.
[SFEDIT -8]  Parameter SKNT is not in the data set.
[SFEDIT -9]  SFEDIT cannot continue with invalid parameters.
Any ideas what I'm doing wrong? I've attached the station table I used, the data file, and the error messages. 

Thanks!
Dave
