pasting script code from webpages into the blender text editor

I have been trying this for months and it does not seem to work. Could someone try it and tell me if it works on their machine? The paste option is grayed over on my computer. There may be aproblem with my computer. Here is a webpage with script. Thanks http://www.pasteall.org/49483/python

I figured it out. I had to hit the new button at the bottom of the page to paste the script. I then saved it as a py file to my desktop. Why do the above 2 scripts by pink vertex not load? Should they load in 2.69.10? “Source file is in the addon search path” is the error I get.

Works for me, you need an active object with follow path constraint and a target set to a curve already…

How did you install the addon, and what else is printed in the system console?
