Re: what does this error message mean

Hello
Probably the functions you're using have variables that haven't been 
defined as numbers. For example , if you try:
  In[112]:=
FindMinimum[a*x^2, {x, -1}]
FindMinimum::nnum : The function value 1.a is not a number at {x} = {-1.}

This is because Mathematica can't know what is the value of "a" 
because it hasn't been defined before, so it can't find a minimum etc..
Please send more information about your specific problem, so we can be 
more helpful...
