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
