thanks for answering, but what i need is to show a comment wish explain smth about the cell so that the user doesn't write smth wrong.
For exemple if my cell has to have a number% btw (2% to 4%) the user has to write a number in btw. and the message will be when i cross that cell " the rate of bla bla is btw 2% and 4% "
Ok, look at the sample excel sheet I attached. If you scroll over the yellow squares, you'll see a comment box pop up. Is this what you are referring to?
