Dear Group,

I am having trouble getting SplineFit to work.  Here is a simplified
version of what I'm trying to do



GET[  "NumericalMath`SplineFit.m`"]

pts = {{0, 0}, {1, 2}, {2, 2.5}, {3, 2.75}, {4, 2.9}};

spline = SplineFit[pts, Cubic]

ParametricPlot[spline[u], {u, 0, 4}, PlotRange -> All, Compiled -> True]



When I try to run the ParametricPlot, I get an error message stating
"spline[u] does not evaluate to a pair of real numbers at u =
1.6666666666666665", etc



Thanks in advance for your help.  Regards, Darrell Bosch
