Suppels

I've looked at Agoraphobic's Eclipse Event System Tutorial. One of the features isn't working for me though, where it says copy page. Can you only copy a page and use it in that same event? By this I mean I have 3 doors next to one another, but want them to all do the same event. Rather than typing it out for each separate event, can I just copy the event and paste it next to the other one? When I copy the page then open the other event I can't paste the page.
