>When I try to run one Job, it starts to run, then shows me a message 'Variable 'Sigma' is not found'. I use 'Epsilon', but it's really a Greek letter, which is uses for sum in math (not sure, that it's a Sigma, I forgot the name). This Error message has only two buttons: Ok and Help, so I can not debug. I click OK and now I have another Error message, something like: "Index doesn't match. Recreate Index' with also just two buttons. Very informative!!!! I see, that I'm in serious trouble, but what should I do? What is corrupted?

This looks like an index with a funky expression in it.
