VBScript Running A Stored Procedure - Cannot Return Output as Int

Hello;

I've created a stored procedure that is called upon by a VBScript.  The VBScript passes two varchar parameters to the sp - User Name and Computer Name.  My intent of the SP is to return an integer to be used later in the script.  When the script runs, it errors out with the following error:

 Microsoft VBScript runtime error: Invalid or unqualified reference

I'm specifying the return value in the script as an integer, so I'm not sure where this is going wrong. I've attached the SP in a text file and the script used to run the SP, so if anyone out there can take a look and provide me some assistance I would much appreciate it.  Thank you!

You are combining OUTPUT and RETURN parameters.  Choose one or the other.

This is how you do it with a RETURN parameter:
Your Stored Procedure:
CREATE PROCEDURE dbo.stpMostUsedPCByUserID  
	@userid VARCHAR(50),
	@compName VARCHAR(50)

AS

DECLARE @rtnValue integer

SET NOCOUNT ON;

SELECT	@rtnValue = COUNT(*) 
FROM	LOGON_SESSIONS  
WHERE	userid = @UserID
	AND Computer = @CompName

RETURN @rtnValue

And here is your VBScript:
...
cmd.ActiveConnection = cn
cmd.CommandType = adCmdStoredProc
			
				
sSql = "stpMostUsedPCByUserID"
cmd.CommandText = sSql
						 
With cmd
	.Parameters.Append .CreateParameter("@RETURN", adInteger, adParamReturnValue)
	.Parameters.Append .CreateParameter("@UserID", adVarChar, adParamInput, 50, Left(Right(oSysInfo.UserName,Len(oSysInfo.UserName) -3 ),InStr(Right(oSysInfo.UserName,Len(oSysInfo.UserName) -3),",")- 1))
	.Parameters.Append .CreateParameter("@compName", adVarChar, adParamInput, 50, Left(Right(oSysInfo.ComputerName,Len(oSysInfo.ComputerName) -3 ), InStr(Right(oSysInfo.ComputerName,Len(oSysInfo.ComputerName) -3 ),",")- 1))
End With	

'On Error Resume Next
cmd.Execute
rtnVal = .Parameters.Value("@RETURN")
WScript.Echo rtnVal
'on Error GoTo 0
