How to return values from a SQL Server Stored Procedure and Utilise them in Access VBA

Question

I've set up a Stored Procedure in SQL Server that works fine. I can now call it from VBA, but want to return a value to know if there were any errors etc. The last parameter in my SP is set up as OUTPUT:

@DataSetID int = 0,
@Destination char(1)='-',
@errStatusOK bit OUTPUT

My VBA to call the SP is below, but it won't work now, after adding the new parameter and I'm not sure where I'm going wrong, I keep getting 3708 - Parameter object is improperly defined. Inconsistent or incomplete information was provided.:

Set cnn = New adodb.Connection
cnn.ConnectionString = 
   "DRIVER=SQL Server;SERVER=SERVER\SERVER;DATABASE=a_db;Trusted_Connection=Yes"

cnn.Open cnn.ConnectionString

Set cmd = New adodb.Command
cmd.ActiveConnection = cnn
cmd.CommandType = adCmdStoredProc
cmd.CommandText = "stprMoveDataSet"

Set param = cmd.CreateParameter
               ("@DataSetID", adInteger, adParamInput, , stDataSet)
cmd.Parameters.Append param
Set param = cmd.CreateParameter
               ("@Destination", adChar, adParamInput, 1, stDestination)
cmd.Parameters.Append param
Set param = cmd.CreateParameter
               ("@errStatusOK", adBit, adParamReturnValue)
cmd.Parameters.Append param

rs.CursorType = adOpenStatic
rs.CursorLocation = adUseClient
rs.LockType = adLockOptimistic
rs.Open cmd

How can I get the vba to work with the OUTPUT parameter and make the return value 'readable' by the vba.

EDIT - I've changed the question to be more specifically about returning values and not just about using OUTPUT Parameters.

Set cnn = New adodb.Connection
cnn.ConnectionString = 
   "DRIVER=SQL Server;SERVER=SERVER\SERVER;DATABASE=a_db;Trusted_Connection=Yes"

cnn.Open cnn.ConnectionString

Set cmd = New adodb.Command
cmd.ActiveConnection = cnn
cmd.CommandType = adCmdStoredProc
cmd.CommandText = "stprMoveDataSet"

Set param1 = cmd.CreateParameter
               ("@DataSetID", adInteger, adParamInput, , stDataSet)
cmd.Parameters.Append param
Set param2 = cmd.CreateParameter
               ("@Destination", adChar, adParamInput, 1, stDestination)
cmd.Parameters.Append param
Set param3 = cmd.CreateParameter
               ("@errStatusOK", adBit, adParamOutput, , adParamReturnValue)
cmd.Parameters.Append param

rs.CursorType = adOpenStatic
rs.CursorLocation = adUseClient
rs.LockType = adLockOptimistic
rs.Open cmd
