When I use the following code from a macro call on the menu of Excel it
works fine (changes the format of the top leftmost cells of the sheet but
when I execute it from a function that is used in a cell of the sheet it
does not work.
How can I change the format or content of cells in a spreadsheet from within
a vusual basic function called in a cell ?
