Crystal Report Parameter Fields [Resolved]

[fret]

Hi to all,

I have a problem that keeps bothering me or it's something that I'm missing a little to this. I have a simple reports that would accept the date range as a Parameter Fields, my problems is even though I've supplied the value for the date range when it shows the Report it keeps asking me to enter a discrete values for Parameter Fields["DateFrom"] and ["DateTo"], or this is something that I am missing?

        ParameterDiscreteValue pdvdtfrom = new ParameterDiscreteValue();
        ParameterDiscreteValue pdvdtto = new ParameterDiscreteValue(); 

        ParameterValues dtfrompv = new ParameterValues();
        ParameterValues dttopv = new ParameterValues(); 

                pdvdtfrom.Value = DateFrom.ToShortDateString();
                pdvdtto.Value = DateTo.ToShortDateString();

                dtfrompv.Add(pdvdtfrom);
                dttopv.Add(pdvdtto);

                reports.availedperiodic av = new reports.availedperiodic();
              

                av.DataDefinition.ParameterFields["DateFrom"].ApplyCurrentValues(dtfrompv);
                av.DataDefinition.ParameterFields["DateTo"].ApplyCurrentValues(dttopv);

                av.SetDataSource(d);

Btw, I am using vs2005 bundle with crystal. Thanks.
