Please note that before you have done this, you need to make sure that you have your club's BridgeWebs 'club code' & password correctly recorded in the 'Event Details' screen*. If you haven't done this, you need to rectify this, then come back here and click on that button again.
*NB in later versions of EBUScore, there is no need to return to the Event Details screen in order to amend these details. They can be done on the Internet Functions screen.
