Works fine here.

it gave me some strange output. Anyone can pls let me know if there's
anything wrong with the mathematica help browser?
Load the polynomialfit package as: <<NumericalMathe'PolynomialFit'
In[1]:= <<NumericalMathe'PolynomialFit'
In[2]:= p=PolynomialFit[{1,4,9,16,25,36,49},3]
Out[2]= FittingPolynomial[<>,3]
In[3]:= Expand[p[x]]
Out[3]= {54756., 57600., 60516., 63504., 66564., 69696., 72900., 76176.,
79524., 82944., 86436., 90000., 93636., 97344., 101124.,
...................}
I didn't manage to type out all the output as there are a lot more
numbers...
