Thank you very much for that good suggestion.
Unfortunately, I had already closed the program. Also, I
tried Undo, but the screen said it could not Undo. I
suppose it is because there are 20,000 numbers. Please,
does anyone have any other ideas? I pray this is a
fixable problem, since it will take days to insert the
endotes plus all the text numbers.

I am angry with myself because I bought Go Back but
didn't install it yet. Thank you.
