See the below Mathcad 15 explanation.  You need to convert ec to a vector (rather than leaving it as a range variable).

Thank you for your reply.  I followed below the same steps in prime and worked. However I wanted to modify my function a little different and did not work again. How can you fix this one? why it did not work? I still have difficulty understanding this process. Thank you.
