I am not familiar with this subject, but I think it would be helpful if you were more specific about what you are doing. There are several books on the subject. Are you reading a particular book on programming genetic algorithms? Do you have a particular program in some language that is not working? What is going wrong?

Genetic algorithms have three parts:
- generate a new set of possible solution vectors from the existing set mating two or more solution vectors to make a new one
- using the fitness function to score each solution vector
- selecting those solution vectors with scores over a certain threshold value or by selecting the top N solutions and discarding the rest

And then repeat the process until some criteria like all scores are about the same or the pool of solutions gets too small.
