Reposted a a new Q as it's a different topic.
Thank you all for the calendar examples. I have come to the conclusion that whilst I could change them to suit (bit of a sledge hammer to crack a nut thing), I have my original (Numbers) calendar, which I can still use and will be sufficient for us.
So I have tried to open the document with Send event on a button. I can get it to open the application but not the actual document: "PLANNING.numbers" The path is: /Users/henrybarnett/Desktop/PLANNING.numbers and it can't find it.
When I went back to the script and changed the path (thinking it may not be correct) it changed the application to unknown! Even when that was corrected it failed to find the document.
My question is, what should I do in the specify window OR is there an easier way of doing it?
