Possible to address a value in a nested vector?

[dsochor]

In the attached MathCAD 14 worksheet I'm attempting to create a new vector that is 2 times a particular value within another vector. More specifically, I'd like the (12 position) vector a.d to be 2 multiplied by the second value in all 12 C.ard vectors. How to tell a.d to successively address the second value in each C.ard vector and multiply it by 2?

Like so?

Thanks again Werner, your vector of a vector notation is exactly what I was looking for.
