change modified servo direction

[scott911]

I've followed the steps for the $50 dollar robot and modified both of my HS-311 servos to rotate continuously.  Now here's my problem.  How can I get them to rotate both forward & backwards?

I'm using the Arduino Duemilanove to control the servo.  But, it seems no matter what degree I set the servo to, it always rotates at the same speed and in the same direction  .

PLEASE PLEASE help!....Thanks
