Jerry, I'm sorry that my previous posting was inc0mplete. In order to refer to a numbered equation like you want - give the containing cell a tag, say eqnX, (menu>Find>Add/Remove Cell Tags). Then when inserting the automatic numbering object (menu>Input>Create Automatic Numbering Object) - choose Numbered Equation for the upper right (Counter Type) field - click the radio button "The first cell with the tag" - click eqnX in the bottom field - click OK -- Allan --------------------- Allan Hayes Mathematica Training and Consulting Leicester UK www.haystack.demon.co.uk hay at haystack.demon.co.uk Voice: +44 (0)116 271 4198 Fax: +44 (0)870 164 0565 <iliketrash at aol.com> wrote in message news:8gv8mh$5nl at smc.vnet.net... > In article <8gu6tj$hp4 at smc.vnet.net>, "Allan Hayes" > <hay at haystack.demon.co.uk> wrote: > > > <iliketrash at aol.com> wrote in message news:8gso4r$eep at smc.vnet.net... > > > In preparaing a paper for publication, I find that making automatically > > > (re)numbering things like equations and figures easy since some of the > > > built-in stylesheets are already set up to do this. > > > > > > However, how do I make references (sometimes called cross-references or > > > citations) within ordinary text to equations and figures that are > > > automatically (re)numbered?
