I can't say what I did! I was going to open it and add a macro when I clicked somthing or other and the page went blank! The Icon has a "!" on it. So I went to the backup I made a couple days ago and it too has a "!" on it. Maybe it means is has macros?
But the file that went blank is 37K and the backup is 35. So I'm thinking the data is still there and whatever key I hit just hid it.
I've attached the entire file in the hope the data is still there and someone who knows what they are doing can make it visible!
