Latex "help" needed

Hello,

I would like to label the following as an equation:

Code:

---

\begin{eqnarray*}

Enormous equation here

\end{eqnarray*}

---

I have tried the \label{name of equation} line, but it did not work.



I want to do this because in my latex document I have labeled many equations the following way:

Code:

---

\begin{equation}

\label{name of equation}

equation expression

\end{equation}

---

And I would like my "eqnarray*" to look like an equation for a reader of my document. I need to cite that "eqnarray*" at several places in my document so I really need to label it, but I don't know how to do.



Any idea?
