Problems with "undefined variable" in program

I am working on creating programs to iteratively model a differential equation.

i have been switching subscripts and the order of things, but it just keeps telling me that there is an undefined variable. and conveniently the "error tracing" doesnt actually specify what is undefined, so i dont even know exactly where the problem is.

The indices in the second and third line of your programms are lowercase letter o's and not zeros. And variable o is not defined 😉
