GSS not including sample

Hi, I'm learning GWB, and I have added data into a GSS file, but my last sample is not having the charge imbalance, charge error, or water type calculated, even though the other 11 are being calculated. All the samples have either a data value or 'nd' in each field. I see this message in the calculation report; *N-R didn't converge after 999 its., maximum residual = 1, Xi = 0.0000 Largest residual(s):

followed by a list of data.

I could not find information on this in the Essentials Guide.

Am I doing something wrong?

Thanks in advance!

Kathy

Hi Kathy:

 

Thanks for sending your dataset. It looks like the bicarbonate value in the last column is set to '0.0' - the field should be either blank or set to 'n/d' or similar.

 

I hope that helps,

Thanks Tom, I deleted the 0.0, and that worked.
