Why does "insufficient input arguments" appear? Obviously, all the variables that go into the formula are specified.

Hi,
You haven't called the function, you just ran the function. You need to call the function with all the required arguments after defining the function.

However the error message is about gaussian_plume2 and we are shown gaussian_plume without the 2.
I suspect that you are correct about the cause, but we can't quite prove it.
