```
<form name = "indexSummaryForm">
<table class = "rtmindex">                                                  
    <tr>
        <td class = "rtmcolumntwo">
            <select id = "intraDayFXRateType" name = "intraDayFXRateType" class = "rtmindexselect">
                <option id = "4" selected>SPOT</option>
            </select>
        </td>
        <td class = "rtmcolumnfour">
            <input id = "preMarketOpenInterval" name = "preMarketOpenInterval" class = "rtmindexcell" type = "text" value = "0" />
        </td>
        <td class = "rtmcolumnsix">
            <select id = "intraDayFXRateBehaviour" name = "intraDayFXRateBehaviour" class = "rtmindexselect">
                <option id = "1" selected>Spot Rate</option>
                <option id = "2">Prev. Day WMSpot</option>
            </select>
        </td>
    </tr>

</table>
</form>

```

When I try to submit the form, alert( "test: " + $('#indexSummaryForm').serializeArray()); returns null. Please check and advise what is wrong in the code?
