Mortality coefficients> net migration rate- negative values not being calculated /displayed correctly

[carieh]

Version 18
The rates are not being calculated/ displayed correctly- I am not sure which.

If I enter values in the other production interface of ecopath I should be able to manipulate the values in the mortality coeficients output, mostly by altering the immigration, and emigration value which will alter the net migration rate in the mortality coefficients.

Basically if I enter in a combination of values into other production that would yield a positive net rate, the calculation is fine, but if I enter in a combination that would yield a negative rate, the value does not show up in the output.
