VB Script Help - Please

I'm new to Homeseer and I'm starting to play with scripts on my Hometroller Zee S2.

I have started with the example scripts in the online documentation:-

Sub Main(parms As Object)
ScriptingReferences = System.Management;System.Managment.dll
Dim dvRef as Integer
Dim dv

dvRef = hs.GetDeviceRefByName("Dining room Table lamp")
if dvRef > 0 then
Set dv = hs.GetDeviceByRef(dvRef)
else
hs.WriteLog "Error","Could not find the reference for the device specified."
exit Sub
end if
hs.WriteLog "Info","The address for the device is " & dv.hc & dv.dc

End Sub

But this gives me the following errors:
Apr-26 23:45:33 Error Compiling script /usr/local/HomeSeer/scripts/alarm_part_arm.vb: 'End Namespace' without 'Namespace'.
Apr-26 23:45:33 Error Compiling script /usr/local/HomeSeer/scripts/alarm_part_arm.vb: Not valid as identifier.
