Ok I've taken u'r advice and set up a simple test at http://www.flytier.co.uk/ring/ringlink2.html and it seems to work fine, considering it's on NT. lol You guys can play around with it if you wish as I can remove everything and set up something real a little later on. Thanks for the advice and the software it's great. Lawrence BTW I'll be hanging around for a while as I've lots more to learn.
