May 18, 2021 at 20:52 comment added MassDefect The error message is trying to tell you that you cannot have Subscript[\[Sigma], 1] = 1 or Subscript[\[Sigma], 2] = 2 as part of the specification of With. Subscripts don't always behave how you might expect them to, so it's better to avoid them until you learn more about when they work and when they don't. There are some good posts on this site about possible workarounds if you really need to have a subscript. If you don't absolutely require a subscript, I would use \[Sigma]1 = 1 and \[Sigma]2 = 2.
