Calling the first row in sharepoint list using Caml

Im trying to call the first row from a SP list after a user selects the first option from my dropdown menu ( second option calls second row etc... )

However its calling the last row when i select the first option ( second option calls second last row etc... )

So when Option 1 is selected Jan-2010 i want it to display the first row "Total[0]" but its returning the last row Total[4].

Im new to Caml so any help would be great...

CAML CODE:

             var soapEnv =
        "<soapenv:Envelope xmlns:soapenv='http://schemas.xmlsoap.org/soap/envelope/'> \
        <soapenv:Body> \
                 <GetListItems xmlns='http://schemas.microsoft.com/sharepoint/soap/'> \

DROPDOWN CODE:

            <tr><td><select id="combobox">
            <option value="Jan-2010">Jan/2010</option>
            <option value="Feb-2010">Feb/2010</option>
             <option value="Mar-2010">Mar/2010</option>
                   <option value="Apr-2010">Apr/2010</option>
              <option value="May-2010">May/2010</option>
              <option value="Jun-2010">Jun/2010</option>

                       </select></td>   
                    <td><input type="button" id="RefreshMetrics"  value="Refresh"></td>
                       </tr>

<OrderBy><FieldRef Name='Date' Ascending ='False' /> \
</OrderBy>

should be:

<OrderBy><FieldRef Name='Date' /> \
</OrderBy>

You are sorting the values is descending order, so April is going to be first and January is going to be last.
