Harmonic oscillator quantum physics using transfer matrix

Hello! I'm new to Mathcad (using it this semester in my university, and we are using the Mathcad 15 version, not prime), and i have a problem. I tried to do quantum harmonic oscillator using transfer matrix, as this is the subject right now. The teacher gave us an exemple problem, i tried to re-do it, and i got an error saying "This value must be integer" (it's error from the RR[j] = T(E[j]) line, and the start of the problem is K(i,E) as it seems it doesn't really recognise Vk). My teacher doesn't know exactly what's the problem, so i tried to get help here because it seems the best place.
Does anyone know how can i solve it? Thanks in advance!

What do you think that V[k is? V is a vector, but k is a range (which is an implicit loop).

What do you intend for example K(47, 11) to return as result?

Furthermore your function "K" does not use its argument "i" - which means that the 47 in my example above are irrelevant and your function "r" would always return the constant 1.
