It's difficult to tell what the problem might be with a code excerpt, but you might try Return[Switch[verbosity /. {options}, 0, BestFitParameters /. RegressResult, 1, NMinResultReport] ]; This depends on something like NMinResultReport = {various options} /. RegressResult; in your function. I'd also recommend using True and False rather than 0 and 1 for your options. Yes, we can write Fortran in Mathematica, but why bother, since True is so much easier to read, and more keeping with other Mathematica functions. Regards, Dave.
