vector

I'm working on a zombie game in AS3 where I want a character to be able to move away from a zombie depending upon how close the zombie is. The character also has a destination that it's trying to get too on the screen.

Ok so I have 2 vectors, one pointing to my destination, and one pointing to the zombie which I then invert to get my "away" vector. I then turn the distance between my character and the zombie into a value between 0 and 1. And then I'm stuck on how to get a resultant vector for my character. How would I use my 0-1 value to calculate how much of the away vector is used and how much of the original destination vector is still left if that makes sense? to end up with 1 direction vector to move my character? So if the zombie is right where my character is, then my direction vector = away vector, and if I'm far away from the zombie than my direction vector = destination vector, but how do I calculate the in-between?

Ideally need the answer in AS3.
