Hi Angela,
I think that is something that should work. Can you send me the whole soruce code to call the crystal reports? I am new with ASP.net.
Here is what I found the sample source code for win form written in C#. I don't know why to convert them to VB and don't know where to place the soruce code.

crReportDocument = new CrystalReport1();
//Get the collection of parameters from the report
crParameterFieldDefinitions = crReportDocument.DataDefinition.ParameterFields;
//Access the specified parameter from the collection
crParameterFieldDefinition = crParameterFieldDefinitions["Country"];
//Get the current values from the parameter field. At this point
//there are zero values set.
crParameterValues = crParameterFieldDefinition.CurrentValues;
//Set the current values for the parameter field
crParameterDiscreteValue = new ParameterDiscreteValue();
crParameterDiscreteValue.Value = Frm.OffID.Text; //"Canada"; //1st current value
//Add the first current value for the parameter field
crParameterValues.Add(crParameterDiscreteValue);
//Since this parameter allows multiple values, the discrete value
//object needs to be reset. Destroy the previous instance and create
