    double comission = (Stotal + Ttotal + SVtotal);
    double MSalary = (comission + 3000);

The prompt it seems to be failing on is:

"Please enter your name"

If you are entering in your name, instead of an integer, that's why it is throwing an exception. The scanner would be looking for an integer, which your name is not. You might want to replace:

int name = sc.nextInt();

with:

String name = sc.next();

or something similar to get name as a String.
