creating .nc file variables

Hi,

I'm begginnig to use NCL, trying to create a .nc file and when I try to
write the new variables to the file it's showing an error message (see the
message in the end of this e-mail and the .ncl file attached). I don't
know what am I doing wrong?!

Could someone help me with it?!

Thanks,

Rosa
