Follow Path Stuff

I have been trying to figure out how to work the Follow Path feature and so far have a question. How do I determine the exact frames at which I want my object to follow a particular Path. I know I can set the length using the eval time but I want to know how I would for example have my object follow the path from frame 130-230?

When you parent an object to a curve using Follow Path it will automatically add a modifier to the F-curve. If you want to control the movement you will need to first remove the modifier (click on the X next to the modifier) and then you can keyframe Evaluation time. In your case go to frame 130 set evaluation time to 1 and add a keyframe (I), the go to frame 230 set evaluation time to 100 and add a keyframe.
