Hi
try the following
- select your cells in column B (assumption: you start in row 1)
- goto 'Format - Conditional Format'
- enter the following formula in this dialog:
=COUNTIF($C$1:$C$300,B1)0
- choose a format for these cells
[...]

Just

=MATCH(B1,$C$1:$C$300)

would be faster though.

Hi Aladin
always impressed about your knowledge about perfomance issues!
I thought COUNTIF would be faster. Have you some details about the
performance difference (or a link to a previous discussion)

Regards
Frank
