coefficient of logistic regression

in logistic regression,
I want to know that it is possible to get probability values of each 
predictors by
using following formula for each predictor one by one (keeping constant 
the others)
<<< exp(coef)/(1+exp(coef)) >>>

Dear Ahmet,

This will almost surely give you nonsense, since it produces a fitted 
probability ignoring the constant in the model (assuming that there is 
one), setting other predictors to 0 and the predictor in question to 1. 
What is it that you want to do?

I hope that this helps,
  John
