dear kind people who know excel!

I have a sheet where in column A I have the name of a compnay. In column D
(which is hidden) I have some descriptive info. Is it possible for the info
in column D to come up in a comment box (or any otehr pop up box) when I
hover over a cell in column A? The sheet is being continually sorted so it
needs to be quite robust.

thanks in advance

Rather excel illiterate person!
