 Numerical Response problems can require units. In the problem editing form,
 place the desired unit in the \textbf{Unit} field. For information about
-what units the system accepts, see http://capa4.lite.msu.edu/demolibrary/Links/UnitsSymbolsT2.html.
+what units the system accepts, see \ref{Physical_Units}.
 The computer will accept the answer in any of its accepted unit formats.
 For example, if the answer to a problem is {}``1ft'', the computer will
 accept {}``12in'' as correct.
