Hi Don, For references, you should use cell tags as follows. Select the cell which you want to reference. Then select from the menu Find | Add/Remove Cell Tags which brings up the Cell Tag dialog box. Give the cell a useful name and close the dialog box. Next, when you want to reference the cell, select from the menu Input | Create Automatic Numbering Object which brings up the Create CounterBox dialog. Select the appropriate counter type, and pick the appropriate cell tag (you will also have to select the option "The first cell with the tag:"). A very nice tutorial on this subject by P.J. Hinton can be found at the web site http://www.wolfram.com/~paulh/Mathematica/Notebooks/ Carl Woll Dept of Physics U of Washington On Fri, 5 Jun 1998, -don. wrote: > Hello all, > > first off, if anyone wants to learn how to implement automatic numbering > in a single quick lesson, see H.
