Hi Ted, I assume your variable is local to a package that contains the variable. Apart from the package context I further assume that your module basically does something like: myFit[data_] := Module[{x, f}, f = FindFit[data, a + b x, {a, b}, x]; a + b x /. f ] which yields something like: In[276]:= myFit[{{1, 2.2}, {2, 3.8}, {3, 6}, {4, 8.4}}] Out[276]= -0.1 + 2.08 x$142961 In my opinion, it is never a good idea to return a local variable. One solution is, of course, to use a different variable in your module, so not x, or not to return the fit in terms of x. If returning a model in terms of x is necessary another solution might be myFit[data_] := Module[{x, f}, f = FindFit[data, a + b x, {a, b}, x]; a + b Symbol["x"] /. f ] In[278]:= myFit[{{1, 2.2}, {2, 3.8}, {3, 6}, {4, 8.4}}] Out[278]= -0.1 + 2.08 x Cheers -- Sjoerd On Feb 11, 10:14 am, Ted Sariyski <tsari... at craft-tech.com> wrote: > Hi, > I have a module, which make use of FindFit[data,model,par,x] and > returns the model and a plot of data and the fit curve.
