[jQuery] Ajax serialize()

Hi all, just stumbled across the serialize() method in jQuery..
previously I've been building the data string myself.

However, I seem to be unable to use it right. I have a pretty basic
form set up, and I'm not sure why it's not working.. figure this is a
quick fix and you guys would be able to give me a quick answer. Here's
my HTML:

<form name="details">
                        <fieldset id="main">
                                <legend id="mainLegend"><span 
id="mainLegSpan">Unsaved</span></
legend>
                                <span>Customer Name:</span><input type="text" 
id="custName"
name="custName">
                                <br>
                                <br>
                                <span>Address:</span><input type="text" 
id="address1"
name="address1">
                                <br>
                                <br>
                                <span>Address 2:</span><input type="text" 
id="address2"
name="address2">
                                <br>
                                <br>
                                <span>Address 3:</span><input type="text" 
id="address3"
name="address3">
                                <br>
                                <br>
                                <span>City:</span><input type="text" id="state" 
name="state">
                                <br>
                                <br>
                                <span>State:</span><input type="text" 
id="state" name="state">
                                <br>
                                <br>
                                <span>Postal Code:</span><input type="text" 
id="postal"
name="postal">
                                <br>
                                <br>
                                <span>Country:</span><input type="text" 
id="country"
name="country">
                                <br>
                                <br>
                                <span>Phone:</span><input type="text" 
id="phone" name="phone">
                                <br>
                                <br>
                                <span>Office:</span><input type="text" 
id="office" name="office">
                                <br>
                                <br>
                                <button id="save" name="save">Save</button>
                        </fieldset>
                </form>

and I'm using var data = $("#details").serialize(); to serialize the
data.

Thanks.
