Thanks for the help. I tried to animated the U value but it would always revert the value back to 1 even if i made a key frame. I was messing with the settings in the Motion Path Attributes and when i check the Parametric Length everything started working fine. Im not sure why but now it is fix. I guess that needs to be check and in the tutorial i was following it did not say anything about it. Thanks again. im sure i will have more questions.
