The attached sheet should help.

You have to know that Prime uses two different types of indices.

The literal index you used throughout is only part of the name, just subscripted

To define vectors you have to use the matrix/vector index. Either from the menu or by using the keyboard shortcut [.

Feel free to ask again if you have any further questions.

Thank you so much for the answer. This gave me so much clarity and how I can simplify things with some tweaks.
