I had to go peruse the code to refresh my memory about why Artemis
reports that error message. It seems there are two situations where
this message turns up. One is when math expressions have unbalanced
parentheses, the other is when Artemis finds discrepancies between the
guess, set, and def parameters and the math expressions for the path
parameters. One such discrepancies is an unused guess or def
parameter; another is the use of a parameter in a math expression
without defining it as a guess, def, or set.
When I go through the project looking for mismatched parens or for
discrepancies in the parameters, I am careful to record every such
problem. That's good. Unfortunately, it seems that, when mismatched
parens are found, Artemis complains and aborts the fit without telling
the user where it found the mismatch.
So the bottom line is that Scott is asking me to fix a silly bug,
which I will gladly do.
Regards,
