You definitely do not give enough information.  You didn't actually say
what program you're using.  I'll guess Artemis.

I believe that the error message you see is from one of the "sanity checks"
in Artemis suggesting that the mathematical expression you're using in the
Get-Def-Set window is invalid or somehow not recognized.   Since you
thought it would be better to not tell us what expression for FeN0 you used
that caused the problem was, I'll eagerly guess that you wrote

  def   FeN0    2(sigma2)

which would generate the message above.  "2()" is not a supported
function.   Voila, problem solved!

You are welcome. It's much easier to solve problems when I get to guess
what they are!
