logistic regression: sign of estimates/coefficients

[Ksharp]

" if one sign is opposite, how do I determine the weight of each factor in the final model?"
I don't understand . What do you mean by "weight" ?
Once you got estimator and WOE , you could get Score Card ,no need to "standardizing all factors (X-mean/std) ".
This variable's Score also has different sign with other variables's Socre.
