If this error is being returned for the line:

max = ste*nind_opt + ori;

then either: std, nind_opt or or have not been assigned a value at the time that this line was called. For a very simple example, imagine we had a program that only contained these lines:

a = 1;
c = 3;

d = a + b + c;

We would get an error of "uninitialized variable", because the variable b has never been given a value. If you do not know which variable is uninitialized, you can add print statements before each of the variables. Using our simple example, we would change it to:

a = 1;
c = 3;

print a;
print b;
print c;
d = a + b + c;

After running this code, we should see that the error is on the line that reads "print b". This will tell us that b is not initialized before we try to use it.
