Hi,
A manual selection , coming from outside the spreadsheet.
On a similar question sombody mentioned a function to be found in
http://www.cpearson.com/excel/colors.htm
where it is says the following:
"Excel does not have any built-in worksheet functions for working with the
colors of cells or fonts. If you want to read or test the color of a cell,
you have to use VBA procedure. This page describes several functions for
counting and summing cells based on the color of the font or background.
All of these functions use the ColorIndex property."
Unfortunately my Excell knowledge is too small to be able to build such a
function.
Thank you anyway for trying to help. For the moment I have to work manually
on that sheet.
Felix
