Access :: Statement Doesn't Work Properly

I have written a bunch of T-sql code to my accessdatasource selectcommand. But I am having problem with where statement ! here is my code;

SELECT OWGBP, RTGBP, OWEUR, RTEUR, OWYTL, RTYTL, (SELECT Resort FROM Resort RF WHERE (View = True) AND (RF.ResID = TypePrices.ResID)) As Resortİsmi, (SELECT Destination + ' - ' + CodeOfDest FROM Destination TD WHERE (View = True) AND (TD.DestID = @DestID))
As DestIsmi, (SELECT TypeOFTrf FROM TRFTypes WHERE (TRFTypes.TRFTypeID = TypePrices.TypeOfTRF)) As TrasferTürü, @QADT As ADTSayi, @QCHD As CHDSayi, ([CHDPerCent]/100) As PerCHDCent, (ADTSayi ++ CHDSayi) As Deger, ResID FROM TypePrices WHERE ([View] = True)
And (ResID = @QRes) AND (Deger >= [MinReq]) AND (Deger <= [MaxCap])

And here is my select parameters;

[Code]....

It is a bit long ! I am having problem on last two where declaration. here ;

(Deger >= [MinReq]) AND (Deger <= [MaxCap])

those MinReq and MaxCap columns are int32 columns. But when I run the page it doesnt work properly ! It display the valuse it shouldn't be ! weird thing is, when I display this 'deger', I get the value properly. with this;

Değer : <b><asp:Label ID="Label10" runat="server" Text='<%# Eval("Deger")%>'/></b>

for example I get 8 with this but it dosnt work on where statement.
