Help with script.

I need help with this game I'm working on. I have this script that has one of my AI's to follow a way point that I set up for him but when he gets to where I want him he turns around and goes back and keeps doing it over and over. I was wanting to know if you can edit the script for me and make it so when he gets to the last way point he doesn't turn around and goes back.

Here is the script and thanks if you can.
