function calcCents {

Function declarations require a formal argument list in
parentheses, even if there are no formal arguments:

function calcCents() {

var cents = document.money.cents.value;
var dollars = 0;
var dollars = cents / 100;
var change = cents % 100;
if (change != 00)

The sense of this test is backwards, and there is no
reason to write the value zero as 00.

if (change == 0)

You have a syntax error here. It should be:

function calcCents() {

You were missing the ().

var cents = document.money.cents.value;
var dollars = 0;
var dollars = cents / 100;

You already declared dollars as a variable. There's no need for
multiple declarations.

You wanted just the number of dollars? Then:

dollars = Math.floor(cents / 100);

var change = cents % 100;
if (change != 00)
window.alert("The number of cents you entered is equal to $" +
dollars + ".00");
else
window.alert("The number of cents you entered is equal to $" +
dollars);

If you wanted just the number of dollars, then you don't even need to
check the change, right?

Hope this helps.
