parameter not supplied for stored procedure

Hi

I have been fustrated by a stupid problem as stated in the title.

I did create the appropriate parameters in the Parameters collection and assign them values.

I looped thru the Parameters collection and make sure it matches the stored procedure input parameter list.

But when i execute  myCommand.Execute,  I keep getting an error saying that I did not supply a parameter which that sp expects.  

Can someone tell me what did i do wrong?

the following is the asp code:

Set spCmd = Server.CreateObject("ADODB.Command")
Set spCmd.ActiveConnection = conn2
spCmd.CommandType = adCmdStoredProc

spCmd.CommandText = "dbo.lsp_updateForm4"
spCmd.Parameters.Append spCmd.CreateParameter("transit", adVarchar, adParamInput, 10)
spCmd.Parameters.Append spCmd.CreateParameter("lineNum", adInteger, adParamInput)    
spCmd.Parameters.Append spCmd.CreateParameter("q3forecast", adDouble, adParamInput)    
spCmd.Parameters.Append spCmd.CreateParameter("q4estimate", adDouble, adParamInput)    
spCmd.Parameters.Append spCmd.CreateParameter("q1budget", adDouble, adParamInput)    
spCmd.Parameters.Append spCmd.CreateParameter("q2budget", adDouble, adParamInput)    
spCmd.Parameters.Append spCmd.CreateParameter("q3budget", adDouble, adParamInput)    
spCmd.Parameters.Append spCmd.CreateParameter("q4budget", adDouble, adParamInput)    

with spcmd
     .Parameters("transit") = "00000"
     .Parameters("lineNum") = 1
     .Parameters("q3forecast") = 100
     .Parameters("q4estimate") = 100
     .Parameters("q1budget") = 100    
     .Parameters("q2budget") = 100    
     .Parameters("q3budget") = 100          
     .Parameters("q4budget") = 100          
     .Execute
end with


And the procedure looks like this:

CREATE PROCEDURE dbo.lsp_updateForm4
     @transit nvarchar(10),
     @lineNum int,
     @lastyractual float = NULL,
     @q1actual float = NULL,
     @q2actual float = NULL,
     @q3forecast float,
     @q4estimate float,
     @q1budget     float,
     @q2budget     float,
     @q3budget     float,
     @q4budget     float
