All sorted, I've had a discussion with Matt/shawnbradleyfan and the impression I have now is that all people are to place their max bid and if that is beaten then so be it which I'm happy with but what's stopping the other person from overbidding out of spite and not owning up to it leaving you with a $100 bill over what you paid? screen shots will now be taken once I've made a bid.
Bridge built and thanks to Matt for making this all available, we would all be lost without him.
