Hi
I am having problems with getting a response from any subroutine

I get error number 30107 = The subroutine failed to complete successfully

I have even tried setting Arg(0) to "" but nothing seems to work can anyone help me 
please.

here is my code if anyone can tell me why its not working.

Public Function doSubRout(ByVal sRoutine As String, Optional ByVal Params As String = 
"") As String
' if Connection failed exit function
If Not Connect() Then
MsgBox("No Connection", MsgBoxStyle.Critical)
Exit Function
End If

Dim myErr As New UniErrors

' Exception on UniObjects Error
m_uniobject.ExceptionOnError = True

' Create subRoutine Object
Dim cu As Object = m_uniobject.Subroutine("MVACNOT", 4)

If m_uniobject.Error <> 0 Then
MsgBox("Error: (" & m_uniobject.Error & ") " + myErr.getErrStr(m_uniobject.Error))
End If

Try
' Get date in Universe format
Dim Tod As New UniDate
Dim sDate As String = Tod.GetUniDate(DateAdd(DateInterval.Day, 20, Now)).ToString()

'cu.Resetargs()

' Set subRoutine arguments
cu.SetArg(0, "")
If cu.Error <> 0 Then
MsgBox("Error: (" & cu.Error & ") " + myErr.getErrStr(cu.Error))
End If
cu.SetArg(1, "ZA4")
If cu.Error <> 0 Then
MsgBox("Error: (" & cu.Error & ") " + myErr.getErrStr(cu.Error))
End If
cu.SetArg(2, sDate)
If cu.Error <> 0 Then
MsgBox("Error: (" & cu.Error & ") " + myErr.getErrStr(cu.Error))
End If
cu.SetArg(3, "OW")
If cu.Error <> 0 Then
MsgBox("Error: (" & cu.Error & ") " + myErr.getErrStr(cu.Error))
End If

' call the subRoutine
cu.call()

If cu.Error <> 0 Then
MsgBox("Error: (" & cu.Error & ") " + myErr.getErrStr(cu.Error))
Else
' Display results
MsgBox("Args: " & cu.GetArg(0) & "," & cu.GetArg(1) & "," & cu.GetArg(2) & "," & 
cu.GetArg(3))
End If

Disconnect()
Catch ex As Exception
' Error handling
If cu.Error <> 0 Then
MsgBox(ex.Message + vbCrLf + "UniVerse : Error: (" & cu.Error & ") " + 
myErr.getErrStr(cu.Error))
End If
Disconnect()
System.GC.Collect()
Return ""
End Try

' Return Result
Return "Args: " & cu.GetArg(0) & "," & cu.GetArg(1) & "," & cu.GetArg(2) & "," & 
cu.GetArg(3)
End Function


This is the first line of the subRoutine I need to call
SUBROUTINE MVACNOT(RETURN.SUPPLIER,ACCOM.CODE,REPORT.DATE,SEARCH.TYPE)

When the system calls this subroutine internally it uses the following

SUBR("MVACNOT",@ID,'DATE()','OW')
