(50g) Normal Distribution

I would like the program to take the same arguments as the UTPN function, mean on level 3, variance on level 2, and x on level 1, as my attempt in the first post did. However, if I divide by 2v instead of by 2, I get the wrong answer. Any helpful hints would be appreciated.

What is "2v"?

To get the Normal PDF for a distribution with mean µ and variance σ², normalize the variable x first by calculating (x–µ)/σ. Then apply the Standard Normal PDF Z(), and finally divide that value by σ.

In other words: simply calculate 1/σ · Z[(x–µ)/σ].
