No value for given parameters error when using command parameters in RDC.

Question

I am trying to create a report using RDC with a parameter in the query, but I keep getting "No value for given parameters" error.  Here is the code I use:
Dim creport As CRAXDDRT.Report
Dim appn As CRAXDDRT.Application
Dim datcmd1 As New ADODB.Command
Dim adocn As New ADODB.Connection   
Dim sqltext As String
Dim x As CRAXDDRT.ParameterFieldDefinition
Set appn = New CRAXDDRT.Application
Set creport = appn.NewReport
Set x = creport.ParameterFields.Add("test", 2)
x.AddCurrentValue 0
sqltext = "SELECT Name FROM TestTable WHERE ID={?test}"
Set adocn = New ADODB.Connection
adocn.Open "Provider=SQLOLEDB;Data Source=myDB;UID=xxx;PWD=xxx;"
Set datcmd1 = New ADODB.Command
Set datcmd1.ActiveConnection = adocn
datcmd1.CommandText = sqltext
creport.Database.AddADOCommand adocn, datcmd1
creport.SaveAs "test", crDefaultFileFormat
Set datcmd1 = Nothing
Set adocn = Nothing
Set creport = Nothing
Set appn = Nothing

Hello, Paul;
If you add your database connection to the command object and put fields on your report without the parameter, do you get the report you expect?
These are version 8/8.5 samples but the code is the same:

Once you have added the database connection follow that with the parameter code.

If you add the parameter and put the field on the report, can you pass the value successfully?
