Pie chart sqldatasource issues

I'm trying to databind the pie chart to the sqldatasource, but it seems there are issues (or I'm not doing it right) with DataFieldY.  The sqldatasource will return 2 column of data as follow:
Description     cnt
7 Days            3
30 Days        37
Rest              42
24 Hour         116

Where the "Description" column I assign to "NameField" and "cnt" column I assign to DataFieldY.  Below is my code for the chart.
                            <telerik:RadHtmlChart runat="server" ID="chartRouters" Width="100%" Height="100%" Transitions="true" 
                                Skin="Silk" DataSourceID="sqlDSModem">
                                <ChartTitle Text="Router Status">
                                    <Appearance Align="Center" Position="Top">
                                        <TextStyle Color="White" />
                                    </Appearance>
                                </ChartTitle>
                                <Legend>
                                    <Appearance Position="Right" Visible="true">
                                    </Appearance>
                                </Legend>
                                <PlotArea>
                                    <Series>
                                        <telerik:PieSeries StartAngle="90" DataFieldY="Cnt" NameField="Description">
                                            <LabelsAppearance Position="OutsideEnd" DataFormatString="{0} %">
                                            </LabelsAppearance>
                                            <TooltipsAppearance Color="White" DataFormatString="{0} %"></TooltipsAppearance>
                                        </telerik:PieSeries>
                                    </Series>
                                </PlotArea>
                            </telerik:RadHtmlChart>   

when I run the code, my pie chart looked "weird" and had only 4 lines (not the chart line, but lines extending out from a single point) Looks almost lilke it is not reading the "cnt" column of the data.  

When I go to the immediate window and do the :

?chartRouters.PlotArea.Series(0).DataFieldY(0)

it gave me value of "c" and then DataFieldY(1) is "n" and DataField(2) is "t".  I was expecting to see the actual value when I do that, but it almost like is putting the column field name in the value instead of actual data value?  That is weird.

What is wrong?

thank you!
